ABSTRACT:
The present invention is directed to an optical module, which stabilizes an oscillation characteristic of a laser by means of a simple configuration. To this end, a gain member, a partial reflection section connected to the gain member, and an optical device section connected to the partial reflection section are formed integrally into an apparatus of the present invention. The partial reflection section includes an optically-coupling waveguide section having a first light waveguide connected to the gain member, and a second light waveguide which has an optical axis differing from that of the first light waveguide and which is optically coupled to the first light waveguide and optically connected to the optical device section; and a first total reflection mirror formed at an end of the first light waveguide facing the optical device section.
