Suppression of the self-induced intensity pulsations from cw junction lasers has been achieved by operating the laser with frequency-selective optical feedback. The feedback is achieved by optically coupling a diffraction grating to a laser mirror. The feedback suppresses all longitudinal modes except one or two and thereby eliminates the mode interactions necessary for sustained optical pulsing. The experimental results directly support the previously proposed model for self-induced optical pulsing in semiconductor lasers. (auth)
