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.

WebThe optical bistability from the nonlinear interference filters (or etalons) can be used to achieve optical logic gates. The transmission property of these etalons can be modified … WebApr 1, 2024 · Exciton–polaritons in optical cavities exhibit strong nonlinearities predominantly because of the third-order Kerr-like interactions mediated by the excitonic component. Under quasi-resonant excitation, depending on the energy of the incident laser, it results in the optical limiting or bistable behavior. The latter phenomenon is manifested … forensic veterinarian salary
