  • Résumé

    Silicon photonics has lived an intense research activity in both the industry and academy over the last decade. It enables the generation, modulation, processing, and detection of classical light signals, with cost- effective devices meeting the ever-increasing demands on data speed and bandwidth. More recently, silicon photonics has turned to the quantum world: it has emerged as a novel and promising platform, enabling both on-chip generation and manipulation of quantum states of light. Few groups including us are starting some developments of quantum silicon photonic circuits. Our objectives are to demonstrate complex circuits at a wavelength of 1.55m based on the dense integration of both linear and non-linear on-chip optical functionalities enabling the generation, the routing, the advanced manipulation, as well as the detection, of photonic quantum states. The objective of the PhD is to address the challenge of the photon-pairs generation based on Four-Wave-Mixing process (FWM) and the on-chip light manipulation of these photons. That includes developing some solutions in the extraction of generated photon-pairs and the optical pump rejection, the photon splitting and in the photon pair interferences. Classical and quantum experiments will be performed either at IEF or at the LPMC. The candidate will fully involve in the design, fabrication and characterization of silicon-based components and will work in close collaboration with the LPMC (Nice, France) in the framework of the French ANR project SITQOM.
