“…However, more quantitative estimations of the gain and loss anisotropies due to asymmetric current injection are necessary to pin down the polarization stabilization mechanism(s). Moreover, incorporating two orthogonal and separated current paths in one device could prove the feasibility of asymmetric current injection for electrical polarization control, which could be very useful to realize fast reconfigurable interconnects [11].…”

“…This might open the possibility of using polarization to encode or process information and use VCSELs for an all-optical processing of these data (e.g. [49,50]). However, the width of this hysteresis loop is usually quite small, only about 20 µA in this example which can be regarded as typical.…”

Experiments and their interpretation on polarization dynamics and polarization switching in vertical-cavity surface-emitting lasers operated in the fundamental transverse mode regime are reviewed. Important observations are switching events to a mode with the lower unsaturated gain and the existence of elliptically polarized dynamical transition states after the destabilization of the low-frequency polarization mode. The observations demonstrate the need to consider explicitly the phase properties of the optical field as well as nonlinear effects affecting polarization selection above threshold. Good qualitative agreement is found with a model which takes into account the spin degrees of freedom of the light field as well as of the carriers ('spin-flip model'), if the spin-flip rate is taken to be some tens of 10 9 s −1. This constitutes a strong-though indirect-indication that spin dependent processes are important in polarization selection in the devices investigated.

“…Polarization switching (PS) between the two orthogonal polarization modes (PMs) when the injected current is changed has been experimentally observed and studied for a decade now [1]- [4]. While uncontrolled PS is highly undesirable in many applications, controlled current-induced PS might be interesting as an alternative switching mechanism [5], [6]. However, the dynamics of current driven PS in VCSELs is still unclear.…”

We present an analytical, numerical, and experimental study of the switching time and jitter of current-induced polarization switching in vertical-cavity surface-emitting lasers (VCSELs) as an example of switching in a nonlinear system in the presence of noise. Assuming that the switching is induced by changes in the dichroism, the problem can be reduced to the first-passage-time problem in gain-switched Class-A lasers. The theoretical results show excellent agreement both with numerical simulations based on the full-rate equations model and with experiments performed on oxide-confined VCSELs.
