Emission properties of a single-emitter laser in photonic crystals Pages 488-491

We theoretically study a single-emitter laser in a photonic crystal. We consider a two-level atomic system coupled to a high-quality micro-cavity embedded within a photonic crystal and coherently pumped by an external laser field. We derive analytical expressions for the optical intensity and second order correlation function for the light emitted into the micro-cavity. The cavity field characteristics are highly distinct from that of a corresponding high-Q cavity in ordinary vacuum. We demonstrate enhanced, inversionless, nearly coherent light generation when the photon density of states of the photonic crystal presents a large discontinuity.
