Paper Abstract

The Minilase-II quantum well laser simulator is briefly described. Simulated modulation responses are then compared to experimental data, showing a good agreement between simulation and measurement. The simulator is also shown to distinguish between effects intrinsic to a quantum well laser and those due to external circuitry and device packaging. Next, Minilase-II is used to demonstrate the highly nonlinear effects of quantum carrier heating, including significant increases in low frequency roll off and differential gain suppressio. Finally, the simulator is used in a preliminary analysis of tunneling injection lasers. The analysis shows that tunneling injection results in less quantum carrier heating. However, the analysis also shows a decrease in the net injection of carriers into the quantum well, which offsets the decreased heating and leads to a a reduction in modulation bandwidth.
