Silicon is an ideal material system for integrated optics at telecommunications wavelengths, and the past ten years have produced a variety of exciting device results using silicon nanoscale waveguides. With a combination of CMOS electronics and photonics in the same chip, we can gain control of both photons and electrons on the nanometer scale, while preserving the powerful economics of VLSI revolution. This is expected to be a critical technology platform for optical interconnects and data center applications. Furthermore, silicon waveguides can be engineered for low optical loss and high cladding overlap, while preserving nano-scale modal areas: As a result, it is possible to add highly nonlinear engineered organic claddings to silicon waveguides, in order to create ultrafast nonlinear devices. This talk will review of the Nanophotonics Group's recent work in chip-scale nonlinear optics, while providing a very brief overview of our other projects in biosensing, optomechanics, and mid-infrared photonics. Lastly, a recent initiative, called OPSIS, to create an open foundry for fully integrated optoelectronic devices and systems in silicon will be discussed.
