Theoretical and experimental study of polarization switching in long-wavelength VCSELs subject to parallel optical injection Vrije Universiteit Brussel
We report a theoretical and experimental analysis of the polarization switching found in a single-transverse mode VCSEL when subject to parallel optical injection. We have found a novel situation in which injection locking of the parallel polarization and excitation of the free-running orthogonal polarization of the VCSEL are simultaneously obtained. Analytical expressions for the power of both linear polarizations in the previous steady state ...
