Abstract
A theoretical analysis of the polarization properties of Vertical-Cavity Surface-Emitting Lasers is presented. A model is derived which contains the influence of material (strain in cavity layers, scattering rates, refractive indices of layers) and cavity design (size, number of layers) parameters on input/output characteristics of the system. The electromagnetic field is represented as a superposition of cold-cavity vectorial eigenmodes of the VCSEL cavity. Each eigenmode is characterized by its resonant wavelength, threshold gain and 3D vectorial eigenmode profile. The electromagnetic field is then coupled to semiconductor Bloch equations describing the active quantum well material. The theory is evaluated for the case of two orthogonal HE 11-like modes and a six-band model of quantum well.
