WebNov 7, 2024 · The optical bistable properties and the bistable thresholds (\(U_{\textrm{l}}\) and \(U_{\textrm{u}}\)) depend on the optical nonlinearity. In this hybrid system, threshold of the optical bistability can be reduced by the surface plasmon effect, providing the possibility of realizing optical bistability at lower light intensity than single ... In optics, optical bistability is an attribute of certain optical devices where two resonant transmissions states are possible and stable, dependent on the input. Optical devices with a feedback mechanism, e.g. a laser, provide two methods of achieving bistability. • Absorptive bistability utilizes an absorber to block light inversely dependent on the intensity of the source light. The first bistable state resides at a given intensity where no absorber is used. T…
