Multi-channel optical switch
First Claim
1. A multi-channel optical switch, which changes optical paths, comprising:
- a first input optical waveguide and a first output optical waveguide arranged in parallel to each other;
a second input optical waveguide and a second output optical waveguide arranged in parallel to each other and spaced apart by a predetermined interval from the first input optical waveguide and the first output optical waveguide;
a third input optical waveguide and a third output optical waveguide, and a fourth input optical waveguide and a fourth output optical waveguide arranged perpendicular to the first input optical waveguide and the first output optical waveguide, and the second input optical waveguide and the second output optical waveguide;
mirrors configured to enter on paths between the first input optical waveguide through the fourth input optical waveguide and the first output optical waveguide through the fourth output optical waveguide; and
a mirror actuator for selectively operating the entering of the mirrors.

Abstract
An optical switch enabling optical communications between an input port and an output port of an optical waveguide by minimizing loss error of an optical signal without using a collimator comprised of a separate mediate optical waveguide, lens or the like is provided. The multi-channel optical switch, which changes optical paths, includes four pairs of input optical waveguides and output optical waveguide arranged in parallel to each other, the first pair of input optical waveguide and output optical waveguide facing the second pair of input optical waveguide and output optical waveguide at an angle of 90 degrees, the first input optical waveguide being installed to correspond to the second output optical waveguide, four mirrors installed to enter in optical path directions between the four pairs of input optical waveguides and output optical waveguides, thereby changing the optical paths, and a mirror actuator for selectively operating the entering of the mirror.
