摘要
High quality InGaAs/InP quantum well structures and 1.5 μm MQW lasers, grown by low pressure MOVPE, are reported. PL linewidth, PL peak energy shift, X-ray satellite peaks and transmission spectroscopy have demonstrated that the InGaAs/InP quantum wells were of high quality. The first improvements in T0 and resonance frequency in 1.5 μm MQW lasers are reported. Superior performances due to a quantum effect are: (1) high T0 value, 105 K (15-45°C), (2) large TE/TM mode gain difference, 45 cm-1, and (3) high resonance frequency, 4 GHz/mW 1/2 .
