QDOM : Quantum Dot Optomechanics

Reference contract : ANR07-240 (2012-2016)
LPN leader(s): Loic Lanco, Pascale Senellart
Main goals : Main objectives: QDOM project bridges the gap, at the nanoscale, between two yet distinct research fields: optomechanics of deformable cavities (« Cavity Optomechanics ») and cavity Quantum ElectroDynamics (« Cavity QED »). These two fields utilize an electromagnetic wave trapped in a cavity, to boost its interaction with a mechanical oscillator or with an atom. QDOM project aims at exploring a hybrid interface between these two domains by using a semiconductor quantum dot embedded in an optomechanical cavity, and by taking advantage of the tripartite interaction between confined excitons, photons and phonons.

Reference contract : ANR-11-BS10-001
Coordinator, Partner(s) : J. Bloch (LPN ), A. Bramati (LKB ), C. Ciuti (MPQ ), G. Malpuech (LASMEA )
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 (UMI- Georgia Tech-CNRS ), J. Leymarie (LASMEA ), F. Genty (SUPELEC-Metz )
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. Partners: UMI-Metz (project leader), LPN, Supelec-Metz, LASMEA. Duration: 01/2012-12/2014. (2012-2014)

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.

Reference contract : ANR blanc 2009

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 Lemaitre
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 (LPL), A. Boudrioua (LPL), B. Geffroy (LPICM)
LPN leader(s): Sophie Bouchoule, Alejandro Giacomotti
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)

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.
