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)
