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.
