), high output power (62 mW/facet) 1.3 µm GaInAsP buried graded-index separate-confinement-heterostructure multiple quantum well (GRIN-SCH-MQW) laser diode entirely grown by metalorganic chemical vapor deposition (MOCVD). This laser diode operated in a single longitudinal mode in a relatively wide temperature range of 35°C without any mode hopping. The minimum spectral linewidth of 2.3 MHz was realized at an output power of 7 mW for a laser diode with cavity length of 900 µm. The beam divergence angle is considerably smaller than that of the conventional DH laser diodes. |
