Abstract
A spatial light modulator system includes a concentration layer including an array of optical concentrators, such that each concentrator concentrates a portion of an input light beam. A modulation layer includes an array of light modulators each in optical communication with one of the optical concentrators for modulating the portion of the input light beam. The light modulators are spaced apart from one another in the modulation layer to form gaps between adjacent ones of the light modulators. A coil of each light modulator can surround a Faraday element or core containing a Faraday material to control a magnetic state of a Faraday material responsive to control signals.
