Abstract
We report on the bias-induced polarization changes of optically pumped top-emitting vertical-cavity surface- emitting lasers (VCSELs). Under optical pumping with zero bias voltage, tow orthogonal polarization states along (110) and 110) crystallographic axes are simultaneously observed with small differences in the relative partitioning. The partitioning of the optically pumped output power between the linear polarization states is shown to be strongly dependent on the applied electrical bias. With increased forward bias, the emission polarized to the dominant polarization direction of the electrically pumped output of the VCSEL is enhanced and becomes a dominant polarization states, suggesting that the polarization characteristics of the device under electrical pumping are closely related to the applied electrical current.
