Paper Abstract

We present preliminary results on low-threshold compact edge-emitting laser structures incorporating high-reflectivity 1D photonic crystal mirrors. In addition we present 2-D FDTD simulation results of the mirror reflectivity and application of selective oxidation for the purpose of current confinement, hence reduction of threshold current. 84um cavity length 1D PC lasers are demonstrated to have a threshold current of approximately 5mA, reduced to 1.7mA upon application of oxide confined current aperture.
