WebSilicon optical bistability relies on a fast thermal nonlinear optical effect presenting a 500-kHz modulation bandwidth. We demonstrate, for the first time to our knowledge, optical bistability on a highly integrated silicon device, using a 5‐µm-radius ring resonator. Web2 days ago · Moreover, some optical memories rely on the nonlinear optical effect and thus require a substantialt optical power to operate. This requirement and the opportunity rooted in optical computing have led to the development of many CMOS-compatible optical devices such as modulators ( 29 , 30 ), detectors ( 31 , 32 ), filters ( 33 ), and switches ...
Optical bistability on a silicon chip - ResearchGate
WebOct 4, 2024 · In optical interconnects, nonlinear signals are transmitted through silicon-based waveguide through either two-dimensional or three-dimensional fabrication. Progression in nanotechnology made it viable to arrange light source; laser, medium; waveguide, and detector; and photodiode into a single 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 onward arc im
