Clermont4 : Exciton-polaritons: Physics and Applications

Reference contract : FP7-ITN-235114
Coordinator, Partner(s) : A. V. Kavokin (Universite De Southampton),
LPN leader(s): Jacqueline Bloch
Main goals : The primary goal of this Network is to create a highly skilled body of young researchers capable of internationally competitive research in one of the most quickly developing areas of the modern physical science and technology. The main research objective of the CLERMONT4 network is to facilitate the exploitation of breakthroughs in polaritonics which occurred in 2006-2008. We shall focus on realisation of four prototypes of polariton devices: electrically pumped polariton lasers, micron size optical parametric oscillators, optical logic gates and cavity-based emitters of entangled photonic pairs. In order to realise these goals we have built a consortium of academic teams which have already given to Europe an enormous lead in the international competition with American and Japanese groups to realize practical polariton devices. Furthermore, we bring these academic teams together with an outstanding group of industrial partners capable of effectively driving through the translation of emerging promising new physical demonstrations into devices.

COPERNICUS : Compact OTDM / WDM Optical Receivers based on Photonic Crystal Integrated Circuits

Reference contract : FP7-ICT-2009.3.8b
LPN leader(s): Fabrice Raineri, Rama Raj
Main goals : COPERNICUS targets advances in the physics, technology, modelling, and integration of photonic crystal devices. Key devices include high-speed all-optical gates, low-crosstalk wavelength drop filters, and high-speed integrated photodetectors. These devices rely on very strong light-matter interactions arising from the large, ultrafast nonlinear optical response of III-V semiconductors and the strong resonant field enhancement in photonic crystals. This is ideal for filters and all-optical gates, enabling a dramatic reduction in size and switching energy. Their switching energy*delay product is two orders of magnitude smaller than that of competing technologies. Modelling will consider carrier plasma (spectral and spatial) contributions to the nonlinear optical response and develop a robust optical, thermal and electronic design tool for photonic crystal devices. New levels of photonic crystal integration will be pursued to combine these devices and achieve complex all-optical functions attractive to both medium- and long-term markets. (2010-2012)

Quandyde : QUANtum DYnamics of exciton-polariton conDEnsates

Reference contract : ANR-11-BS10-001
Coordinator, Partner(s) : J. Bloch (LPN ), G. Malpuech (LASMEA ), C. Ciuti (MPQ ), A. Bramati (LKB )
Main goals : The four partners involved in the project propose to study the fundamental properties of polariton quantum fluids in resonators of different dimensionalities and different geometries. Moreover thanks to the high quality of GaAs based samples recently shown at LPN, they will develop innovative polariton devices to explore this physics. - The first task of Quandyde will be the study of propagating polariton condensates and their topological excitations. It is now feasible to observe the generation of solitons, of vortex lattices and explore quantum turbulence effects. Using samples with controlled disorder, we will explore the effect of disorder in the propagation –transition between localised and superfluid phases. - The second task of Quandyde will be the physics of new polaritonic devices. We want to observe the normal and chaotic Josephson oscillations, to build the first polariton interferometer, and to demonstrate polariton Bloch oscillations. Additionally, we plan to develop both from the theoretical and experimental point of view, the study of chains of micropillar cavities, a new paradigm for the physics of non-equilibrium Bose-Hubbard phases.

VESUVE : ANR Blanc 2011 - VErtical cavity Surface emission laser operating in deep UV rangE

Reference contract : ANR Blanc SIMI3 - VESUVE
Coordinator, Partner(s) : A. Ougazzaden (Unité Mixte Internationale- Georgia Tech-CNRS),
LPN leader(s): Sophie Bouchoule, Anthony Martinez, Abderrahim Ramdane, Gilles Patriarche
Main goals : Along with visible and IR spectroscopy, UV and deep-UV (DUV) laser absorption spectroscopy is extensively used for chemical and biochemical sensing. However, the primary limitation of current UV optical sensors is the existing sources of UV light. The replacement of the wide-spectrum deuterium-halogen or filtered narrow-band mercury discharge lamps, by more compact and reliable sources would be extremely attractive. In this context, the objective of VESUVE project is to develop a semiconductor-based surface emitter operating in the deep-UV range, using novel wide-bandgap materials systems including BAlN and (In)AlGaN semiconductors. VESUVE project plans to demonstrate at first an optically-pumped UV-VCSEL emitting at 280 nm. RC-LEDs and VCSELs with (In)AlGaN/Al(Ga)N –based active region and combining both AlN/BalN semiconductor Bragg mirrors and dielectric mirrors will be developed. Lasers in external-cavity configuration (VECSEL) will also be envisaged. The OP-VCSEL is a first step towards the development of next-generation optical sensor systems with coherent, reliable, and low-power consuming UV light source components.

PEROCAI : Perovskite in microcavities

Reference contract : ANR Blanc 2010 (ANR-10-04)
Coordinator, Partner(s) : E. Deleporte (LPQM ), J. Even (FOTON ), P. Audebert (PPSM )
LPN leader(s): Karine Gauthron, Jacqueline Bloch, Sophie Bouchoule
Main goals : Vertical microcavities in the light-mater strong coupling are intensively studied due to the interest in coherent and stimulated effects in such systems as polariton lasing and Bose Einstein condensation in the solid phase. These effects have been recently demonstrated in “classical” inorganic semiconductors and most of the physics is done at low temperature. Until now, attempts to study these physical processes with molecular materials have failed.In this draft, we propose to use organic-inorganic molecular quantum wells inside a vertical microcavity to demonstrate stimulated effects at room temperature. The molecular quantum wells used in this study belong to the perovskite family. Because the strong coupling regime in vertical microcavities containing perovskites has been achieved at room temperature and because of the wide tunability of its exciton perovskite material is a good candidate to realize vertical microcavities and study these polaritonic effects. The physics of these new polaritons is unexplored. Therefore, polariton relaxation efficiency and dynamics will be studied. Finally, experiments designed to observe stimulated effects on these polariton states will be performed.

DOC-FLUC : Détection « on-chip » des fluctuations quantiques de courant de nano-systèmes

Reference contract : ANR blanc 2009
LPN leader(s): Frédéric Pierre
Main goals : The project is to develop and exploit the capabilities of on-chip noise detectors to investigate electronic transport in mesoscopic conductors. On-chip detectors allow a well-controlled and optimal coupling to noise sources, giving access to high-frequency noise and to high moments of noise (at least the third one). Conversely, the intimate coupling between detector and source gives rise to back-action, which needs to be modelled and accounted for. (2009-2014)

MANGAS : Magnetization manipulation in ferromagnetic GaMnAs

Reference contract : ANR Blanc
LPN leader(s): Aristide Lemaître
Main goals : The magnetization state of a ferromagnetic object or particle is a simple and reliable bit of information. It has been used for decades to store information on hard disk drives. In these devices the magnetization state is manipulated by applying short and localized magnetic field pulses. Going beyond this technique, with alternative methods to magnetization manipulation, would tremendously extend the possibilities of information storage and logic using ferromagnetic cells or circuits. Our project is at the very heart of this topic. We propose here to investigate several schemes to manipulate the magnetization using non-magnetic stimuli in a specific ferromagnetic material: the ferromagnetic semiconductor GaMnAs. In this compound the origin of the ferromagnetism is singular, and stems from the composite nature of this compound: both magnetic and semiconducting. The magnetic phase is induced by the exchange coupling between the spin of the carriers (holes) and the manganese magnetic moments. This property gives rise to a strong interplay between the magnetic and the semiconducting properties, a unique opportunity to explore new roads to magnetization manipulation. In this project, the techniques we will be investigating are manipulations using i) spin currents for magnetization switching or domain wall motion ii) strain iii) light pulses and iv) electric fields. Several of them have already been demonstrated in metallic systems, we plan then to evidence the modifications brought about by this carrier induced ferromagnetism. This comparison will give invaluable information about the mechanisms at work in magnetization manipulation. Some others, like electric field induced manipulation, are specific to ferromagnetic semiconductors. We will then determine how versatile these techniques can be to obtain large changes of the magnetization direction and amplitude. (2010-2013)

OLD-TEA : Organic Laser Diode : A low laser-Threshold Experimental Approach

Reference contract : ANR Blanc 2010
Coordinator, Partner(s) : N. Fabre (LPL), A. Fischer (UTP), A. Fischer (LPL), A. Boudrioua (LPL)
LPN leader(s): Sophie Bouchoule, Alejandro Yacomotti
Main goals : The final objective of the OLD-TEA project is to demonstrate lasing action in an organic heterostructure under electrical excitation. Intermediate achievements will consist in demonstrating a narrow spectrum (< 0.1 nm) OLED in a microcavity, and an optically-pumped organic laser in a microcavity. More specifically, the current project deals with the realization of organic laser diodes in a low laser-threshold experimental approach, making use of high-quality factor microcavities. Lasing action will indeed require the design of a laser cavity with a laser threshold current at a level compatible with achievable current densities in OLEDs. Two approaches will be developed and explored in the framework of this project: a vertical extended micro-cavity surface emitting OLED, and a photonic crystal microcavity with infiltrated organic material. Project duration:36 mois – Partners: LPL – Univ. Villetaneuse (project leader), LPN, and LPICM-Ecole Polytechnique. (2010-2013)

CALIN : High quality factor cavities, slow mode waveguides and slow light by nonlinear interaction

Reference contract : ANR- 10-BLAN-1002
Coordinator, Partner(s) : K. Bencheikh (LPN ),
Main goals : Il n'existe pas à notre connaissance de micro/nano-résonateur à fort facteur de qualité où la lumière soit ralentie. Dans les résonateurs à cristal photonique, les facteurs de qualité peuvent dépasser 10^6. Cependant la lumière s'y propage avec des vitesses de groupe de l'ordre de c (>c/20). Les raisons conduisant à la difficulté à ralentir d’avantage la lumière dans des résonateurs de petite taille a été analysée théoriquement dans deux articles récents. Ils pointent sur l’impossibilité d’accorder en phase le mode lent et le mode du résonateur, ainsi que sur l’augmentation de la sensibilité aux pertes lorsque que la vitesse de groupe est réduite. Nous proposons dans ce projet de contourner ces problèmes en obtenant la lumière lente par l’effet OCP et non pas par la seule ingénierie géométrique. Deux avantages majeurs en résultent : l’existence de paramètres indépendants de la géométrie pour adapter les modes et la possibilité de contrôler optiquement, voire dynamiquement, le ralentissement. Plusieurs verrous seront adressés : - Compréhension de l’interaction lumière lente-microcavité dans divers régimes temporels: le partenariat LCFIO-LPN-FOTON permet d’adresser les divers aspects théoriques et numériques en profitant de savoirs-faires bien établis et complémentaires. - Démonstration expérimentale de la lenteur du mode photonique : le partenariat LPEM-LPN permettra de réaliser un montage expérimental basé sur une détection hétérodyne avec une résolution temporelle picoseconde et sub-picoseconde avec pointe diffusante. Ce montage permettra une « visualisation » des modes ralentis. (2010-2013)

MICPHIR : Nouveaux MIcro-emetteurs a Cristaux-PHotoniques moyen-IR coherent accordable de puissance

Reference contract : ANR Blanc 2010
LPN leader(s): Alexios Beveratos, Isabelle Sagnes
Main goals : L’objectif du projet MICPHIR est de surpasser les limitations des lasers monofréquences moyen-IR (2-3 µm) à semiconducteur et à l’état solide. Le but est de développer un nouveau composant photonique fonctionnel de haute cohérence spatiale/temporelle de forte puissance basé sur les technologies des semiconducteurs III-V Sb et GaAs (VCSEL, cristaux photoniques, membrane). L’application principal visée est un capteur multi-gaz compact utilisant des techniques de spectroscopie d’absorption CRDS (Cavity Ring-Down Spectroscopy). Ce système permettra de réaliser un capteur de gaz pour des applications allant de l’environnement, la climatologie, la sécurité industrielle, la biologie, la médecine. Pour surpasser les limitations des capteurs - utilisant des lasers DFB -, le consortium MICPHIR veut développer une source laser dans la configuration VECSEL (Vertical-External-Cavity Surface Emitting Laser), alliant compacité, large accordabilité, haute puissance et haute cohérence spatiale/temporelle. L’étude physique complète sera réalisée (qualité de front d’onde, bruit d’intensité, largeur de raie, dynamique) afin d’extraire les paramètres physiques critiques. Un VECSEL est un laser à semi-conducteur formé par un 1/2 VCSEL - composé d’un miroir de haute réflectivité et d’une zone de gain à puits quantiques -, un gap d’air de ~cm, et classiquement un miroir concave diélectrique qui ferme la cavité (coupleur de sortie). Ce projet MICPHIR a pour but, dans une première étape, de repousser les performances de ce type de laser : l’objectif est d’atteindre de fortes puissances (>100mW) en conservant un faisceau TEM00 pour des diamètres >100 µm et une faible largeur de raie, ceci en environnement sévère (température); régler le problème des sauts de modes et rendre sa polarisation stable insensible au feedback. Ces améliorations seront obtenues grâce à de nouveaux ingrédients physiques et technologiques: grâce à une gestion thermique du 1/2-VCSEL par collage, à de nouvelles structures à puits quantiques émettant jusqu’à 2.8 µm, et d’autre part grâce à un composant miroir à cristaux photoniques/effet plasmon à semiconducteur GaAs (coupleur de sortie) présentant de nouvelles fonctionnalités. Parmi ces fonctionnalités, on peut compter: un filtre accordable en longueur d’onde pour éviter les sauts de mode, et/ou un filtre à plasmons pour contrôler l’état de polarisation; un miroir à lentille diffractive pour contrôler et stabiliser le mode transverse fondamental dans une cavité sub-millimétrique. Dans une dernière étape, ce composant sera intégré dans un micro-support en matrice silicium, afin d’obtenir un micro-système laser totalement fonctionnel et robuste pour les éventuelles applications. L’objectif final est de tester ce micro-émetteur dans un système CRDS multi-gas à haute sensibilité. Ce capteur permettrait la détection et l’analyse de gaz in-situ des molécules d’intérêt suivantes: CH4, NH3, HF, NO2, CO, isotopes H2O, CO2. Ces nouveaux concepts et propriétés de composants seront généralisables à d’autres gammes spectrales pour applications photoniques variées.

INCLINE : INductively Coupled PLasmas for CMOS –compatible etchINg of high performance III-V integrated laser sourcEs

Reference contract : ANR-09-BLAN-0019 - INCLINE
Coordinator, Partner(s) : P. Chabert (LPP )
LPN leader(s): Sophie Bouchoule
Main goals : The goal of this project is to develop a thorough understanding of the plasma kinetics and plasma-surface interactions in inductive discharges based on CMOS compatible chemistries (i.e. on gas chemistries deployed in the CMOS industry, as for example Cl2-HBr-O2 containing chemistries), that will form the fundamental basis for the subsequent demonstration of a CMOS-compatible etching process used in the fabrication of a high-performance integrated III-V laser source. The three main objectives of the project are: i) to build the necessary fundamental expertise on plasma kinetics and plasma-surface interactions in inductively coupled plasma using CMOS-compatible chemistries, a domain where many open questions still exist; ii) to exploit this new expertise to propose a CMOS-compatible chemistry for the fabrication of an integrated laser micro-source with deeply etched mirrors, and to demonstrate for the the compatibility of this fabrication with a 200mm or300-mm etching tool; iii) to introduce monitoring techniques that may be suitable for the control of the III-V etching process reliability. The INCLINE project will associate two research labs with well-recognized expertise in III-V laser processing belonging to the French ICT community, and three labs belonging to the plasma community with a well-recognized expertise in the field of plasma physics in inductively coupled discharges using reactive gas, including plasma kinetics and plasma-surface interactions. The project outcomes relevant for the fields of plasma science and technology, and optoelectronic engineering are i) to provide a 2D plasma model of CMOS compatible chemistry that will correctly depict real etching tools; and to develop a 2D III-V etching ; ii) to demonstrate the successful CMOS-compatible fabrication of two demonstrators (an edge emitting micro-laser with deeply etched mirrors and of an edge emitting laser with facet cleaving and optical coating steps replaced by an etching step). –Project partners: LPN-CNRS (project leader) and LTM (CNRS – UJF Grenoble), LPP (CNRS –Ecole Polytechnique), INL (CNRS – Ecole Centrale Lyon), and IMN (CNRS – Université de Nantes). – Project Duration: 36 months (Nov 2009 – Nov 2012).

LPN leader(s): Lorenzo Bernardi, Ali Madouri, Laurent Couraud, Edmond Cambril
Main goals : The goal of this project is to significantly improve the performance of non contact atomic force microscopy (NC-AFM) by developing new force sensors (or cantilevers). In this AFM mode, the cantilever (CL) is embedded in a positive feedback loop that oscillates at the CL resonance frequency while another feedback loop maintains its oscillation amplitude at a pre-set value. The signal that is used for imaging is the resonance frequency of the CL, which varies under the influence of the tip-sample forces. This mode has proved to be the most sensible in the last 10 years. It is the only one giving true atomic resolution on a large variety of surfaces (metals, covalent or ionic semiconductors, covalent or ionic insulators,...). The technique, after been used in UHV for a long time, is now adapted to ambient conditions and liquids, especially for applications in biology. In NC-AFM, the minimal detectable force, fixed by the thermal fluctuations of the CL, is inversely proportional to the square root of the resonance frequency and the quality factor. Improving the instrument sensitivity can then be done by increasing the resonance frequency and/or the quality factor of the CL. (2009-2012)

BOSEFLOW1D : Bose condensate fluids in 1D systems: microcavity polaritons and ultracold atoms

Reference contract : Chaire Junior RTRA 2011-020T-BOSEFLOW1D
LPN leader(s): Alberto Amo
Main goals : Quantum gases in reduced dimensionalities present new fundamental properties which strongly depart from their 3D counterparts. 1D systems are very attractive due to the fact that propagation properties are still present while interesting phenomena related to localisation-delocalisation, role of interactions and fermionisation effects in a boson condensate can be studied in a controlled environment. So far, much of the experimental and theoretical efforts in this direction have been undertaken in ultracold atomic condensates, which constitute text-book examples of bosonic condensates in equilibrium. While still much physics remain to be unveiled in this system, polariton boson condensates in semiconductor microcavities provide an excellent platform in the solid state for the study of a rich variety of quantum fluid effects in confined geometries. The main goal of this project is the study of the propagation, superfluidity and excitations in polariton condensates in 1D. These studies will be performed in collaboration with an experimental group working on 1D atomic Bose-Einstein condensates, profiting from mutual exchanges to understand the specifities of each system.

INTREPID : Détecteur plasmoniques infrarouges

Reference contract : ANR-P2N
LPN leader(s): Jean-Luc Pelouard
Main goals : Détecteur plasmoniques infrarouges (2011-2013)

PhLARE : Photonic-crystal micro-laser arrays for the mid-infrared

Reference contract : RTRA
LPN leader(s): Isabelle Sagnes
Main goals : L’objectif de ce projet est le développement de matrices bidimensionnelles de micro sources laser à émission par la surface, fonctionnant à température ambiante et dans la gamme spectrale du moyen infrarouge (5 µm < lambda < 15 µm). Les lasers seront basés sur l’architecture à cascade quantique, tandis que les micro résonateurs exploiteront les structures à cristaux photoniques. Le fonctionnement à température ambiante, et l’optimisation des performances (augmentation de la puissance émise, réduction du courant de seuil…), exploiteront le savoir faire en termes de conception et de fabrication récemment développé par le LPN et l’IEF. Le 2eme objectif – plus exploratoire – sera d’utiliser les propriétés des modes photoniques sur lesquels le laser fonctionne (il s’agit des états de bord-de-bande de la structure photonique) pour obtenir une accordabilité en fréquence et une plus grande puissance de sortie. Partenaires : Projet porté par le LPN, IEF. (2010-2013)
