Abstract: A reflective magneto-optic spatial light modulator (MOSLM.TM.) assembly has a nonmagnetic protective housing that receives, positions, and protects a spatial light modulator (SLM) chip that is formed from relatively fragile magneto-optic material from deformations caused by mechanical stress and by excessive temperature changes. The assembly further has a channelled ingress and egress of incident electromagnetic radiation, such as visible and coherent light, to and from the SLM chip.

Abstract: Methods of operation and details of chip design to realize gray-scale capability in magneto-optic chips. Individual pixels are operated in three states by the addition of a stripped state to the usual stable magnetized states in either direction. Varying thicknesses of film are employed along with stacked identically patterend chips operated in tandem. Pixel divisions are divided into individually-addressible areas of differing sizes which can be operated in different combinations to provide varying levels of brightness through each pixel position.

Abstract: Methods of operation and details of chip design to realize gray-scale capability in magneto-optic chips. Individual pixels are operated in three states by the addition of a stripped out state to the usual stable magnetized states in either direction. Varying thicknesses of film are employed along with stacked identically patterned chips operated in tandem. Pixel divisions are divided into individually-addressible areas of differing sizes which can be operated in different combinations to provide varying levels of brightness through each pixel position.
