Electrically injected photonic crystal edge emitting quantum dot light source

This study addresses the need for integrable, electrically injected microcavity light sources for compact photonic integrated circuits and presents a novel electrically injected 2D PC-based quantum dot edge emitting light source with coupled PC waveguide that avoids carrier recombination in PC air-holes and allows for easy integration with PC planar waveguides. It is envisaged that ultimately, with a single dot in the PC microcavity, the coupled device will be an ideal vehicle for the study of cavity quantum-electrodynamics (CQED) phenomena.
