Abstract
An optical device comprises an optical waveguide having, as a basic unit, a core layer of a liquid having a relatively high refractive index and a clad layer having a relatively low refractive index and covering said core layer, and a heat-generating means for heating a part of said core layer to form a vapor bubble in said liquid of said core layer.
