Opt. 10 (1998) 87-96 | Subject: | Optics; Adaptation and Self-Organizing Systems | physics.optics adap-org cond-mat nlin.AO quant-ph | Abstract: | We investigate the effects of the electron-hole spin dynamics on the polarization fluctuations in the light emitted from a vertical cavity surface emitting laser (VCSEL). The Langevin equations are derived based on a rate equation model including birefringence, dichroism, and two carrier density pools seperately coupled to right and left circular polarization. The results show that the carrier dynamics phase lock the polarization fluctuations to the laser mode. This is clearly seen in the difference between fluctuations in ellipticity and fluctuations in polarization direction. Seperate measurements of the polarization fluctuations in ellipticity and in polarization direction can therefore provide quantitative information on the non-linear contribution of the carrier dynamics to polarization stability in VCSELs. | Source: | arXiv, physics/9706020 | Services: | Forum | Review | PDF | Favorites |
