Abstract :
In this work, we present a scheme to accelerate the convergence of a quasi-3D spectral laser diode simulator. It is demonstrated that the acceleration scheme allows the number of Fox-Li roundtrips to be substantially reduced. The accelerated spectral laser model is then used to simulate a narrow index guided 980 nm tapered laser. The width of the simulated emission spectra is found to agree well with the measured spectra using an appropriate value of the spontaneous emission coupling factor.
