Abstract

Modeling of laser performance has become increasingly important as the performance requirements for lasers in telecommunications applications have become more demanding. The utility of modeling properties such as optical gain is tied to the use of multiquantum well (MQW) structures to improve laser performance. A multidimensional design space must be mapped out. At the same time, development of low cost, uncooled laser modules highlights the temperature dependence of laser performance. The T₀ parameter empirically describes the temperature sensitivity through I_th = I₀exp(T/T₀). For InGaAsP based lasers, T₀ of 60-80 K near room temperature indicates substantial degradation of laser performance at elevated temperatures.
