Abstract
An optical switch comprises a sheet-type main member including a plurality of optical waveguides linearly extending to intersect with each other on a plurality of intersections and an optical fiber member, while the main member and the optical fiber member are connected with each other through a connection member. The main member has notches provided to traverse the optical waveguides. The connection member includes a plurality of optical waveguides linearly extending for transferring optical signals between the optical waveguides and the optical fiber member therein. The main member and the connection member are divided from a continuous member on the same substrate, while the optical waveguides are obtained by dividing continuous optical waveguides on the same substrate.
