ABSTRACT:
An optical switch easy to adjust optical parts without using a catoptric system and an optical add/drop multiplexer using the optical switch are provided. Between an input light outputting collimator device20and an output light inputting collimator device21provided to face each other at a predetermined spaced interval, a drop light inputting collimator device22and an add light outputting collimator device23fixed and held on a movable holding member24ain common are moved forward and retreated, and thereby a switching is conducted.
