Optical manipulation of quantum dot excitons strongly coupled to photonic crystal cavities

Abstract

In this paper, we review some recent cavity quantum electrodynamic (CQED) experiments with single quantum dot exciton coupled to photonic crystal cavities, performed in our group. We show how the coupled quantumdot/cavity system can be used to modulate light with at a very fundamental level with very low power and discuss some applications of these low power modulators.
