Abstract

Disclosed is herein an optical switch, which has advantages of an MEMS optical switch and a waveguide optical switch including a small electric power consumption, an easy packaging process, and a fast switching speed. The optical switch includes an input waveguide connected to an input optical fiber through which an optical signal is inputted, and a plurality of output waveguides connected to a plurality of output optical fibers through which the optical signal is outputted. An actuator is positioned between the input waveguide and the output waveguides, and has an MEMS structure including a fixed part and a moving part connected to the fixed part by a spring to move by a predetermined force. Additionally, a plurality of moving waveguides are assembled with the moving part of the actuator and move in the same direction as the movement of the moving part in such a way that first ends of the moving waveguides correspond in position to the input waveguide, and second ends of the moving waveguides correspond in position to the output waveguides.

Description

technical field [0001] The present invention generally relates to an optical switch used as an essential part of a wavelength division multiplexing (WDM) optical communication network, and more particularly, the present invention relates to an optical switch and a method for manufacturing the same, the The optical switch has a fast response speed, consumes little power, and can be used in a precise and easily packaged process because the optical switch can be connected to an optical fiber according to a simple operation. Background technique [0002] In general, an optical switch plays a role in changing the path of an optical signal transmitted via an optical fiber in a WDM optical communication network, and recent research on optical switches is focusing on optical switches implemented based on micro-electromechanical system (MEMS) technology and the use of thermal energy The induced change in refraction is realized on the optical switch. [0003] In a MEMS optical switch...
