A phase-locked laser diode array with three index waveguides is described. The array has a novel structure which prevents channels from being etched back. As the result, the waveguide elements in the array are very uniform. A stable 180/sup 0/ phase mode oscillation is obtained up to 50-mW output power in the single longitudinal mode and three supermodes are observed simultaneously above 50-mW output power. The near-field patterns and the far-field patterns of these supermodes are in good agreement with the theoretical results.
