High-Q Photonic Crystal Hetero-Slab-Edge Microcavity Laser for Index Sensing

Abstract

We design a photonic crystal hetero-slab-edge microcavity sustaining surface mode with high quality factor similar to 5.4x10(5) and index sensitivity of 591 nm/refractive index unit by mode-gap effect. Lasing actions from real devices are also observed. (C)2009 Optical Society of America
