Abstract
Self‐aligned structure InGaAsP/InP DH lasers with emission wavelengths near 1.3 μm are studied. A cw threshold of about 100 mA is obtained in these lasers with cavity lengths of about 300 μm at a heat sink temperature of 25 °C. Light output increases linearly with current for outputs of 10 mW per facet and no kinks appear. Fundamental‐transverse and single‐longitudinal mode oscillation, and stable operation of fundamental‐transverse mode against injection current, are achieved. A cw operation up to 72 °C is obtained with a laser.Keywords
