Abstract

An improved current-to-light model, including bandgap renormalization, is applied to high-performance vertical-cavity lasers to determine appropriate values for Auger recombination and leakage currents in InGaAs quantum wells. The model is then used to analyze the threshold temperature sensitivity of various cavity designs, showing the design changes needed for broad temperature stability. The practical limits on low-threshold devices are then examined. Finally, a current-apertured design is analyzed in detail, showing stabilized single-mode operation with improved efficiency
