Abstract

In various applications of VCSEL’s, it is useful to be able to control the polarization of the output light. It has been shown experimentally that switching between linearly polarized states can be achieved by external feedback which enhances one of them [1]. In recent work [2] we developed and analyzed a theoretical model describing these experiments and found many similar changes in stability and sustained dynamical switchings. Xew Hopf instabilities arising from the delay in the feedback loop were also found.
