Master 2

  • Nanostructured optical waveguide array for hybrid isolator on silicon

  • 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.
