Anti-resonant reflecting photonic crystal vertical-cavity surface-emitting lasers

Abstract

Anti-resonant reflecting photonic crystal structure is employed in vertical cavity surface emitting lasers (VCSELs) to achieve photon confinement in lateral direction. Such a design is promising in supporting large aperture single-mode emission. In the configuration, a hexagonal array of high-index cylinders which run vertically in the cladding region are introduced in the top of the VCSEL p-type DBR mirror region. The transverse modal property of the proposed structure, especially leakage loss, has been investigated. An optimum design for the minimum radiation loss while maintaining single-mode operation has been discussed in this paper.
