ABSTRACT:
There is provided an optical switch that can be easily manufactured and has hardly any optical loss. A movable board-like electrode disposed in parallel with a fixed board-like electrode with a predetermined space therebetween by a flexible beam-like element, at least two mirrors fabricated on the surface of the movable board-like electrode, and at least three V-shaped grooves for fixing optical fibers are concurrently fabricated by applying an anisotropic etching to a single crystal silicon having its surface of (100) crystal face. In this case, two opposed mirrors are fabricated such that their mirror surfaces form a right angle, and two parallel V-shaped grooves are formed at positions opposed to the mirror surfaces at an angle of 45° thereto. An output side and an input side optical fibers are received and fixed in one of the two V-shaped grooves and the other groove, respectively.
