Abstract
An optically bistable, nonlinear optical device that produces an output that follows two hysteresis loops for an optical intensity variation input at a given frequency. One hysteresis loop follows a clockwise path of development, the other follows a counterclockwise path when the input field or optical intensity is ramped to a large value and returned again to a small value. These features of the device are effectively engineered by controlling the temperature of the input and output faces of the device, allowing optical logic gating and multiplex operation.
