Entangled Photon Pairs Produced by a Quantum Dot Strongly Coupled to a Microcavity

Entangled Photon Pairs Produced by a Quantum Dot Strongly Coupled to a Microcavity

We show theoretically that entangled photon pairs can be produced on demand through the biexciton decay of a quantum dot strongly coupled to the modes of a photonic crystal. The strong coupling allows us to tune the energy of the mixed exciton-photon (polariton) eigenmodes and to overcome the natural splitting …
