An integrated twin-guide (ITG) laser which has an active waveguide for laser oscillation and an external waveguide for the light output is proposed as an integrated-optics laser or as a new semiconductor laser, and its properties are investigated theoretically and experimentally. ITG lasers were constructed in the form of an AlGaAs multiheterostructure, and their preliminary characteristics were obtained with both optical pumping and current injection at room temperature. The end mirrors of the active waveguide were fabricated by a back-sputtering method. The axial mode selectivity was predicted by the analysis and observed experimentally. (auth)
