Abstract

PURPOSE:To make a device small-sized, especially for an optical IC, by prividing a protective film on the surface of a substrate, providing a branch waveguide consisting of an optical propagation medium, in a U-groove provided on the protective film, providing a buffer layer on this branch part, and also providing an electrode for making a light beam selectively pass through to a light emission side waveguide, on side layer. CONSTITUTION:On a substrate 22 of a sapphire, etc., a protective film 231 is formed by SiO2, etc., and on the film 231, an optical branch waveguide 23 consisting of a U- groove 232 and an optical propagation medium 233 embedded in this groove is formed. On a branch part 236 of a light incidence side waveguide 234 and a light emission side waveguide 235, a buffer layer 24 is formed. On the layer 24, a voltage applying electrode 251 and an opposed electrode 252 for making a light beam from the light incidence side waveguide selectively pass through to the light emission side are provided. The optical propagation medium 233 uses a material such as PbTiO3, etc. whose refractive index is larger than that of the substrate 22, the film 231 and the buffer layer 24. The electrodes 251, 252 are formed by Au, Al, a transparent conductive substance, etc. In this way, it is possible to obtain an optical waveguide branching device which is small-sized and thin, and excellent in its integration degree, and is used for a small- sized optical device.
