  • Abstract
    We show theoretically that the loss difference of about 10% is required between the main mode and the side mode for a semiconductor laser to oscillate in single-longitudinal mode. The DFB laser has been found to meet this requirement, and a side-mode suppression of more than 30 dB was observed under high-speed direct modulation.
