Optical switch

摘要

The optical switch includes: an input port from which a beam is input; a dispersing unit that disperses the beam input; a condensing unit that condenses the beam dispersed; a mirror that reflects the beam condensed; and a plurality of output ports from which the beam reflected is output. The mirror rotates around a first axis so that the beam reflected enters one of the output ports, and also rotates around a second axis perpendicular to the first axis so that an intensity of the beam output is attenuated.
