ABSTRACT:
An optical switch, wherein the first and second output ports (optical fibers) are disposed on the opposite sides of the input port (optical fiber) so as to form acute angles with respect to the input port, the input port and the first output port are optically coupled to each other through a first mirror surface, and the input port and the second output port are optically coupled to each other through a second mirror surface. The incident angles of an incident light beam with respect to the mirror surfaces are equalized, and optical path lengths between the input port and the first and second output ports are equalized. The actuator inserts and withdraws the second mirror surface on a position at the front of the first mirror surface.
