ABSTRACT:
A multi-stable optical device and system which utilizes an active optical element such as a spatial light modulator (SLM) in a feedback path configuration. The elementary system consists of a pair of image element (pixels) on the SLM whose input and outputs are coupled to each other by purely optical means. In another arrangement, multi-stable performance is achieved by optical path geometry defining a single pixel which performs in conjunction with a feedback path. Analysis is provided identifying the equilibrium states of the system as well as those equilibrium states which are stable in nature.
