Abstract :
In this work, we experimentally study the temperature characteristics of tensile-strained GaAsP-AlGaAs single-quantum-well-heterostructure (SQWH) laser diodes. Specifically, we systematically examine the dependence of the characteristic temperature (T/sub O/) on the quantum well composition in broad-area stripe lasers with identical quantum well widths (115 /spl Aring/) and cavity lengths (750 /spl mu/m).
