Abstract
A reflective mode, magneto-optic spatial light modulator (MOSLM) device has one or more pixel elements formed from a selected magneto-optic material with a respective pair of coincident current select electrical conductors associated with each pixel where at least one of the conductors is planar and thereby develops a reflector surface that reflects incident radiation, such as polarized light of an optical beam, which has passed at least through an associated pixel back through the magneto-optic material and resident single magnetic domain of the pixel.
