OPTICAL SWITCH USING MULTI-MODE INTERFERENCE TYPE OPTICAL WAVEGUIDE AND FABRICATING METHOD THEREOF

摘要

PURPOSE: An optical switch using a multi-mode interference type optical waveguide and a fabricating method thereof are provided to prevent the cross talk in an initial state by separating sufficiently a moving optical waveguide from a fixing optical waveguide. CONSTITUTION: An optical switch using a multi-mode interference type optical waveguide includes a fixing optical waveguide, a moving optical waveguide, and an actuator. A multi-mode interference type photo-coupler is symmetrically divided into a left and a right side. The fixing optical waveguide(110a) is formed by fixing one of the divided photo-couplers on a substrate. The moving optical waveguide(110b) is symmetrical to the fixing optical waveguide. The actuator(150) is fixed to the moving optical waveguide.
