Paper Abstract

We compare the threshold gain and modal discrimination of a range of large aperture VCSELs intended for high-power single-mode operation. The threshold gain is calculated using a gain eigenvalue solver that enforces the threshold condition of the mode (gain = loss). In this way, gain guiding is included automatically. We find that confining the gain to a smaller area than the mode results in excellent threshold gain and modal discrimination, due to the large difference in modal overlap factors between the fundamental and the second order mode.
