Abstract
We have theoretically and experimentally studied optical emission from the side faces of mesa structures for vertical-cavity surface-emitting lasers (VCSELs). The results of spatially resolved spectral measurements show that a new type of lasing modes is found in VCSELs with circular mesa structures, which corresponds to the pi mode propagation along the mesa diameter with reflection from the sloped walls and the bottom Bragg mirror.
