Abstract

The characteristics of polarization self-modulation in vertical-cavity surface-emitting lasers (VCSELs) were experimentally and numerically investigated. Polarization self-modulation was induced by using feedback from an external reflector with a quarter-wave plate to rotate the polarization direction by 90°C. A switching frequency of 9.18 Ghz was obtained. Polarization self-modulation was simulated taking into account the feedback from the external reflector. Nonlinear gain was phenomenologically described. In general, the results suggest that the dynamical behavior of the interband is the dominant effect for polarization self-modulation in the investigated regime.
