Abstract

We investigate the correlation between the electrical and optical characteristics of selectively oxidized vertical-cavity surface-emitting lasers (VCSELs). Electrical derivative analysis is used on VCSELs to study the electrical performance and its correlation with the polarization-resolved optical powers and spectra. Characteristic features are shown in the IdVldI curves near major transition points of VCSEL operation. From the IdVldI curve we are able to precisely identify important operating currents such as the lasing threshold, the higher-order mode lasing current, and the cut-off current. Five operation regions are defined in the polarization-resolved L -I curves based on these currents and their temperature dependences are also studied.
