Simulations of light–current and spectral characteristics of InGaAlAs/InP semiconductor lasers

The light—current and spectral characteristics of semiconductor lasers are simulated by using models with and without inverse mass for radiative transitions with and without fulfilment of the wave-vector selection rules. The best agreement between the theory and experiment is obtained for a model without inverse mass with radiative transitions without fulfilment of the selection rules. The obtained results are discussed.
