Manipulating Light on a Si chip

Photonics on chip could enable a platform for monolithic integration of optics and microelectronics for applications of optical interconnects in which high data streams are required in a small footprint. Recent results in Si Nanophotonics have shown the ability to guide, filter, bend and split light on Silicon chips using nano-size structures. In this talk I will review the challenges and achievement in the field of Nanophotonics and present our recent results. Using highly confined photonic structures we have demonstrated ultra-compact passive and active silicon photonic components with very low loss. The highly confined photonic structures enhance the electro-optical and non-linearities properties of Silicon. We demonstrated several active components including all-optical and electro-optic low power switches and modulators on silicon.
