We present a numerical approach to the simulation of dielectric waveguides that is free of spurious modes and is based on the solution of an eigenvalue problem for the two transverse components of the magnetic eld. We introduce a new discretization which has several computational advantages. In particular, by careful design of the discretization procedure(More)
We describe a two-dimensional model for quantum-well lasers that solves self-consistently the electrical and optical equations. The model includes a wavelength-and position-dependent gain function which is derived from a quantum-mechanical calculation. We have also incorporated the effects of strain into the model, through an anisotropic parabolic band(More)

We successfully employ polynomial acceleration of Gummel's method for decoupling the equations describing steady state semiconductors. We present numerical results which demonstrate that the speed of convergence has been increased up to a factor of four. The polynomial acceleration is based on an analysis of Gummel's method as a non linear fixed point(More)
