Claim Text:
1. A semiconductor device comprising: a substrate; a monolithic gain region forming a first semiconductor region disposed on the substrate and operable to produce optical gain in response to current injection, including an optical waveguide layer extending from a first end of the substrate to a second end of the substrate opposite to the first end, the optical waveguide layer including an active layer formed on the upper surface of the substrate, a reflective mirror provided at one end of the optical waveguide layer, and an exit aperture on the other end of the optical waveguide layer for emitting optical energy; a first electrode over a first portion of the gain region having a first length L a second electrode over a second portion of the gain region having a second length L wherein I
