ABSTRACT:
A semiconductor laser apparatus having an optical waveguide made of a semiconductor crystal, an optical cavity made of a mirror facet for reflecting light into the optical waveguide, and an optical gain region occupying at least part of the optical waveguide for generating an optical gain when powered. The optical gain region exists over a linear portion of the optical waveguide. The remaining portion of the optical waveguide is at least partially bent in structure.
