Comparison of IV-VI semiconductor microcavity lasers for the mid-infrared with active regions of different dimensionality

In this paper, we present a comparison between IV-VI vertical-cavity surface-emitting lasers (VCSELs) containing active regions of different dimensionality but with a nearly identical optical design of the cavity. In addition, the same optical set-up as well as pump source was used for laser excitation and characterization. This allows studying the influence of the dimensionality of the active material on the laser properties.
