Abstract

Provided is a spatial light modulator capable of miniaturizing cell size and reducing the loss associated with the miniaturization. A spatial light modulator (SLM) is equipped with: a plurality of microcells (C) with a cell size of less than 1 μm, or a cell size equal to or smaller than the wavelength of signal light; and a black matrix (BM). A predetermined number (four) of microcells (C) adjacent to each other are defined as unit cells (UC), and the black matrix (BM) surrounds each unit cell (UC).
