Silicon is evolving as a versatile photonic platform with multiple functionalities that can be seamlessly integrated. The tool box is rich starting from the ability to guide and amplify multiple wavelength sources at GHz bandwidths, to optomechanical MEMS. The strong confinement of light in ultra small structures also enables the generation of strong optical forces. We have recently shown that nonlinear optical forces can enable controllable manipulation and synchronization of photonic and micromechanical structures. These advances should enable future micro-optomechanical systems (MOMS) with novel and distinct functionalities.
Another research area that recently has emerged is nonlinear optics using silicon photonics. matching of parametric nonlinear optical processes such as four-wave-mixing (FWM) We demonstrated FWM-based frequency conversion in waveguides using as little as 1 mW of pump power in a ring-resonator geometry, and ~100 mW of pump power over bandwidths exceeding 800 nm in a straight-waveguide device.
