Ultraviolet Lasing Characteristics of a GaN Photonic Crystal Defect Emitter

Abstract

The fabricated GaN photonic crystal defect emitter demonstrated multimode lasing with a low optical pumping threshold of pulse engergy similar to 0.15 mu J. The device exhibited high spectral purity and enhanced spontaneous emission factor, beta similar to 0.045. (C) 2006 Optical Society of America
