Abstract :
A new finite-difference algorithm has been developed and will be shown in this presentation. The algorithm is used to calculate the detailed time evolution of the transverse mode profiles of VCSELs. The VCSELs are based on InGaAs-GaAs quantum well structures. Effects of pumping current and refractive index profiles will be investigated in detail. The simulation results will be compared with other results the use the rate-equation model
