Title:
【発明の名称】光スイッチング装置
Document Type and Number:
Japanese Patent JP3031707
Kind Code:
B2
Abstract:
A light activated switching device is disclosed in which the receipt of a light signal is used to switch a light beam between two output ports. The input light beam is reflected from an interface between two regions having different indices of refraction when the light signal is present. The reflected light beam then exits through the first output port. In the absence of the light signal, the two regions have the same index of refraction, and the light beam passes through both regions and exits through the second output port.
