Quantifying Loss Mechanisms in InGaAsP/InP Quantum Dash and Quantum Well Lasers

As quantum dash laser designs gain technological maturity, there is a need to investigate performance limiting factors. We simulate monolithic ridge waveguide quantum dash (QDash) and quantum well (QW) lasers in the InGaAsP/InP-system to investigate the mechanisms limiting device performance at elevated temperatures. Our findings are compared to experimental data obtained for representative device...
