Abstract
We report the fabrication of photonic crystal surface-emitting lasers using an MBE air-hole retained growth method. We demonstrate the achievement of single-mode oscillation and observe a single-lobed, linearly polarized beam. We also use three-dimensional coupled wave analysis to calculate the effects of using different air-hole shapes, which determine the beam shape and polarization. A single-lobed, linearly polarized beam can be obtained by modifying the air holes from circular to a tilted-corn shape after growth.
