Numerical studies of longitudinal distribution of gain and photon density profiles in laser diodes
Abstract
A novel numerical scheme for solving the rate equations describing spatial gain and photon density profiles is presented. The method does not require spatial averaging of the carrier and photon intensity, thus allowing spatial and temporal profiles to be displayed at any time. The method is shown to predict accurately the behaviors of two laser diodes (with reflectivity values of 0.3 and 0.0001). This model is useful in the simulation of ultrashort optical pulse generation. The model also explains the appearance of two optical pulses observed experimentally as being due to relaxation oscillation and not to mirror reflection.
