| Abstract: | High output-power and narrow spectral-linewidth operation of 1.3-μm gain-coupled distributed feedback lasers with grating are reported. The fabricated output power of 230 mW and a linewidth of 100 kHz by reducing optical confinement in multiple quantum wells to improve the single-mode stability at high output-power operation |
