Full vectorial electromagnetic modeling of vertical-cavity surface-emitting diode lasers by the plane wave admittance method

Abstract

We present a new three dimensional, fully vectorial optical modeling of oxide confined as well as shallow relief vertical-cavity surface-emitting laser. Our model is based on the combination of the plane wave expansion method with the method of lines resulting in a fast and accurate computational technique. We carry out hereby a comparison between the Plane Wave Admittance Method (PWAM) and other numerical approaches for VCSEL optical modeling and show very good agreement. Furthermore, this procedure makes it possible to find optimal basic computational parameters for the PWAM in the case of VCSELs.
