ABSTRACT:
A spatial light modulator includes: a modulating layer having optical properties changeable depending on the strength of an applied electric field; a pair of transparent electrode layers sandwiching the modulating layer for generating the electric field; and a photoconductor layer disposed between one of the pair of transparent electrode layers and the modulating layer for generating a photocurrent corresponding to the illumination by light, wherein the photoconductor layer has a quantum efficiency of more than 1. A method for fabricating the spatial light modulator is also disclosed.
