Abstract

We present continuous wave laser emission in a photonic crystal microcavity operating at 1.5 mu m at room temperature. The structures have been fabricated in an InP slab including a single layer of self-assembled InAs/InP quantum wires (QWrs) as active material. Laser emission in air suspended membranes with thresholds of effective optical pump power of 22 mu W and quality factors up to 55000 have been measured. (C) 2009 Optical Society of America
