Three-Dimensional Photonic Band-Gap Structures For Single-Photon on Demand Sources

We describe a practical implementation of a semi-deterministic photon gun based on the stimulated Raman adiabatic passage pumping and the nonlinear tuning of the photonic density of states in a photonic band-gap material. We show that this device allows deterministic and unidirectional production of single photons with a high repetition rate of the order of 100 kHz. We also discuss specific 3D photonic microstructure architectures in which our model can be realized and the feasibility of implementing such a device using Er³⁺ ions that produce single photons at the telecommunication wavelength of 1.55 microns
