Paper Abstract

We review a relatively simple model for VCSEL polarization noise, which is based on the adiabatic elimination of the carrier spin dynamics, and show how this 2-dimensional model can often be further simplified to a 1-dimensional (Kramers) model. Experimental verification for the validity of these models comes from a series of experiments on proton-implanted and etched-post VCSELs. We quantify the amount of linear and nonlinear birefringence and dichroism, we demonstrate a polarization-type of four-wave mixing, and discuss the correlated modal intensity fluctuations in the two polarization modes. Finally, we discuss the jump statistics of a VCSEL with stochastic polarization switches, and present a time-resolved observation of the polarization evolution during such a switch.
