    We have recently shown that a micropillar laser with saturable absorber can behave analogously to a biological neuron but with characteristic timescales one million times faster. It can generate optical action potentials and possess a relative and an absolute refractory period. By coupling several of these lasers it is possible to fabricate neural networks with new functional properties. These systems, while being very recent and still in the course of developments, represent an alternative path for optical processing of information with respect to traditional architectures. The goal of the PhD project is to set up experiments in view of understanding the physics of such systems to contribute to the design and fabrication of the samples that take place in the LPN clean room facilities. In particular the candidate will explore the physics of coupled micropillar lasers, the propagation of nonlinear waves and the implementation of novel bio/neuro-inspired functionalities. More info

  • Level : Master2
    Theme : Optic of Semiconductor nanoStructures Group (GOSS)
                Elaboration and Physics of Epitaxial Structures (ELPHYSE)

    Silicon will be the future of integrated photonics. Garnet should be associated to Si to provide integrated optical isolation. C2N has developed an oxide-free bonding technique [1] of both materials that enables preserving any structuration included in the silicon waveguide. Such a nanostructuration is a very versatile tool for designing tailored structures dedicated to advanced optical functions [2].
    The internship aims at studying specific design for optical isolators [3]. LUMERICAL commercial simulation tool will be used to fix the geometrical parameters of the waveguide array. C2N Marcoussis has large clean room facilities where devices will be fabricated, first on SOI to validate the design, and later on hybrid garnet/Si to demonstrate the isolation operation. Measurements will be performed on an end-fire set-up.
    This internship is undertaken in the framework of the ANR ISOLYIG project.
    The student may acquire knowledge in device simulation, clean-room nano-fabrication techniques and experimental optical characterization.

The internship can be followed by the start of a PhD program. More info
