ABSTRACT:
An optical switch includes a polymer sheet having an optical waveguide extending linearly therein, keep plates holding the polymer sheet therebetween, and driving means. The polymer sheet has a notch provided to traverse the optical waveguides, and the keep plates each have an opening at a position corresponding to the notch. The opening has an elongated shape along the extending direction of the notch at least on a surface of the keep plate in contact with the polymer sheet. The driving means is for selecting a course of light by switching open and closed states of the notch by pushing and not pushing the polymer sheet via the opening.
