MAXIMUM OUTPUT POWER AND MAXIMUM OPERATING TEMPERATURE OF QUANTUM-WELL LASERS

An efficient phenomenological model describing the temperature depende nce of the output power of multiquantum well (MQW) lasers is presented . The model can predict all the general features of the experimental r esults. The effect of series resistance, thermal resistance, cavity le ngth, leakage current, and facet reflectivity on the maximum achievabl e power are analyzed in a systematic manner. The calculated maximum op erating temperature (T-m), defined as the heat sink temperature at whi ch the saturated output power vanishes due to heating, is in reasonabl e agreement with reported experimental results.
