Abstract:
1. A total reflection type optical switch comprising: silica optical waveguides having first silica optical waveguides which are formed on a substrate and connect an input port and a first output port, and second silica optical waveguides which intersect the first silica optical waveguides and are connected to a second output port; and a polymer which is provided in a intersecting location where the first and second silica optical waveguides intersect each other and which switches an optical signal input into the input port to be output to the first output port or second output port; wherein the silica optical waveguides further comprise a plurality of third silica optical waveguides which are provided generally perpendicularly in a longitudinal direction of the polymer and arranged parallel to each other along the longitudinal direction.
