ABSTRACT:
An optical switch wherein a stripe layer of a compound semiconductor whose refractive index is changed by changing a carrier concentration thereof is disposed so as to cut off both optical waveguides at a position of a longer diagonal line of an intersection portion between the optical waveguides formed on a substrate of a compound semiconductor and intersecting each other at a predetermined angle, and the refractive index is changed by causing current to flow to the stripe layer.
