A combination of a single quantum emitter (a semiconductor quantum dot) with a semiconductor optical nanocavity has been employed to demonstrate devices ranging from optical switches and modulators controlled with sub-fJ energies, to quantum sources.
Methods to improve single photon generation via photon-blockade in a photonic-crystal cavity with a strongly coupled quantum-dot are presented. With realistic system parameters, significant improvement in second-order-auto-correlation g2 (0) (from 0.93 to 0.79) is achieved.
We demonstrate all-optical switching based on a single quantum dot coupled to a photonic crystal cavity. The quantum-dot mediated interaction between the signal and control beams occurs at the single-photon level.
