Tunable single-photon frequency conversion in a Sagnac interferometer [PDF]
Wei-Bin Yan, Jin-Feng Huang, Heng FanWe study the single-photon frequency conversion of a five-level emitter coupled to a Sagnac interferometer. We show that the unity conversion efficiency can be achieved either in resonance or off-resonance case under the ideal condition. In particular, the frequency of the output photon can be controlled by the frequencies and Rabi frequencies of the external driving fields.View original: http://arxiv.org/abs/1308.0086
