WebFeb 19, 2024 · An optical bistable setup contains a nonlinear optical sample whose output beam is applied in a feedback system to manage the transmitted light through the element itself. Combination of the incident and feedback beams causes the curves of output intensity ( I3) versus input one ( I1 ), become a steep S-shape ( Fig. 1 ). Fig. 1. 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…
