Abstract
Quantum-well lasers are expected to have several advantages such as low-noise and high-frequency dynamic performance for optical communication systems. However, there have been only a few reports of quantum-well lasers using In-GaAsP/InP alloys, which are suited for these systems. We report the characteristics of the spectral linewidth and the relaxation resonance frequency fr in InQaAsP muitiquantum-well (MQW) lasers, compared with conventional double-heterostructure (DH) lasers.
