    "abstract": "We investigate the effects of the electron-hole spin dynamics on the\npolarization fluctuations in the light emitted from a vertical cavity surface\nemitting laser (VCSEL). The Langevin equations are derived based on a rate\nequation model including birefringence, dichroism, and two carrier density\npools seperately coupled to right and left circular polarization. The results\nshow that the carrier dynamics phase lock the polarization fluctuations to the\nlaser mode. This is clearly seen in the difference between fluctuations in\nellipticity and fluctuations in polarization direction. Seperate measurements\nof the polarization fluctuations in ellipticity and in polarization direction\ncan therefore provide quantitative information on the non-linear contribution\nof the carrier dynamics to polarization stability in VCSELs.",
