LIGHT CONTROL DEVICE

摘要

An optical control apparatus includes: an optical input/output port to which light is input from outside or from which light is output outside; a spatial optical modulator that emits light entering from the optical input/output port towards the optical input/output port and has polarization dependence; a condensing element that is disposed between the optical input/output port and the spatial optical modulator and optically couples the optical input/output port and the spatial optical modulator; and a polarization control element that is disposed between the condensing element and the spatial optical modulator, controls a polarization state of input light to cause the input light to have only a single polarization direction, and outputs the input light controlled. Accordingly, a more downsized optical control apparatus is provided.
