Abstract

High-performance strained InGaAs/AlGaAs lasers fabricated from material grown by atmospheric pressure organometallic vapor phase epitaxy are demonstrated in a variety of structures. The results suggest that the poorer performance observed in the longer wavelength, more highly strained structures is due to an increasing density of interfacial defects even in quantum wells (QWs) of subcritical thickness. Despite this, a graded QW structure improved the performance of highly strained QW lasers, presumably because it reduces lattice mismatch at the active region interfaces. Long-lived InGaAs QW lasers are demonstrated, and strained layer materials are applied to two kinds of two-dimensional laser arrays with performance comparable to GaAs QW lasers
