Abstract:
1. An optical vector matrix multiplier comprising: a plurality of light sources, each operable to radiate light of intensity u fan-out optics arranged to expand the light radiated by the light sources in one dimension; a spatial light modulator comprising a plurality of light modulating zones, each zone receiving light from one of the light sources and being operable to modulate the intensity of said received light by a factor of v fan-in optics arranged to focus the modulated light onto a plurality of light detectors wherein the fan out optics, spatial light modulator, and fan-in optics are arranged such that an intensity of light proportional to is received at each light detector; and wherein the fan-out optics comprise guided-wave optical components, and wherein the fan-out optics comprise a partially-guiding wedge plate.
