Optical Transparency Using Interference Between Two Modes of a Cavity
arXiv:quant-ph/0603044 · doi:10.1103/PhysRevA.74.053817
Abstract
In electromagnetically-induced transparency (EIT), the absorption of a probe beam is greatly reduced due to destructive interference between two dressed atomic states produced by a strong laser beam. Here we show that a similar reduction in the single-photon absorption rate can be achieved by tuning a probe beam to be halfway between the resonant frequencies of two modes of a cavity. This technique is expected to be useful in enhancing two-photon absorption while reducing losses due to single-photon scattering.
