Abstract

An optical switch includes plural pairs of ports and first lenses, each of the ports emitting light in a diffused manner or receiving light input thereto in a collected manner, and the first lenses respectively collimating light emitted from the ports; a second lens that collects the light collimated by the first lenses; and an inclinable mirror that reflects the light collected by the second lens at different angles toward the second lens. A position of a first lens is adjusted based on a first distance between a core of the second lens and a portion of the second lens through which light collimated by the first lens passes.
