Abstract
An optical switch includes a polymer optical waveguide that is a plate material basically made of polymer and a drive element. The plate material has optical waveguides that extend linearly within the plate material and a cut provided such that it traverses the optical waveguides. The drive element selects a path of light by reducing and increasing a gap of the cut.
