Abstract
Disclosed herein is an optical switch for changing over a running direction of a light passing through an optical waveguide between a first direction and a second direction by moving a switching member disposed on an optical path of an optical waveguide. The switching member has a plurality of switching positions for selectively guiding each of lights of at least two different wavelengths into the first direction or second direction.
