Abstract:

We report on photon emission from a high finesse optical cavity containing a Lambda-type three level atom. A Raman-like adiabatic passage is used, where the stimulating laser is replaced by the cavity vacuum.

Abstract:

Most schemes used for the generation of single photons rely on spontaneous emission events in parametric down conversion. A scheme is proposed for generating of emission of one photon into a single, predetermined mode of the radiation field in response to a trigger event. The photon is emitted from an atoms strongly coupled to a high-finesse optical cavity, and the trigger is a classical light pulse. Simulations show that the temporal behavior of the emission probability can be controlled, since it depends on both the cavity decay rate and the shape of the trigger pulse.
