Optical bistability on a silicon chip

Weba silicon device layer (refractive index ~ 3.5) clad with silica (refractive index ~ 1.44). The MZI comprises input and output 3-dB directional couplers, one interferometer arm acting as the resonance pathway is evanescently coupled to a racetrack ring microresonator, and the other arm acting as the coherent background WebIn this project, we exploit mechanical bistability for silicon photonic MEMS switches. This mechanism can lead to an overall drastically reduced power consumption for the optical switch. We developed a compact bistable photonic switch architecture using advanced FEM and FDTD simulation tools and successfully demonstrated the bistability concept.
