OPTICAL SWITCHER

摘要

PROBLEM TO BE SOLVED: To provide an optical switcher capable of transmitting an incident light onto one input port to a plurality of optional output ports. SOLUTION: The optical switcher is provided with; input ports placed on an extension of input optical path of m (m is a natural number of 2 or over) rows; output ports placed on an extension of output optical path of n (n is a natural number of 2 or over) columns; and translucent moving switch mirrors 311 to 3mn placed at grating points of a matrix comprising m-rows of the input optical paths and n-columns of the output optical paths to switch the input optical paths and the output optical paths. The switch mirrors 311 to 3mn are placed so that the mirror remoter from the input port has a higher transmissivity.
