摘要：
The configuration of a liquid crystal switch capable of reducing attenuation in an optical switch, and an optical reception device and an optical switch network that use this liquid crystal switch device are described. The liquid crystal switch device includes optical switches that perform ON/OFF switching of light beams by applying a voltage to the liquid crystal. The attenuation is further reduced by installing the ends of the optical fibers in depressions (or holes) that are formed in the substrate on which the switch elements are formed and in the liquid crystal encapsulation substrate.
