Since the birth of nonlinear optics, researchers have continually focused on developing efficient nonlinear optical devices that require low optical powers. Silicon nanophotonics has emerged as a highly promising platform for such devices and for enabling massively parallel, integrated optical and electronic devices on a single chip. The key feature for nonlinear photonics in Silicon is the strong light confinement that enables both a high effective nonlinearity and tuning of the dispersion, which is essential for phase matching of parametric nonlinear optical processes such as four-wave-mixing (FWM). Using modest continuous-wave powers < 100 mW, we demonstrate a wide range of nonlinear optical devices for ultrahigh bandwidth all-optical processing, chip-based all-optical clocks, and the generation of very high repetition rate femtosecond pulse sources.
