Dark-state polaritons in electromagnetically induced transparency
We identify form-stable coupled excitations of light and matter ("dark-state polaritons") associated with the propagation of quantum fields in electromagnetically induced transparency. The properties of dark-state polaritons such as the group velocity are determined by the mixing angle between light and matter components and can be controlled by an external coherent field as the pulse propagate...
متن کاملAbsorptionless self-phase-modulation via dark-state electromagnetically induced transparency
The closely related phenomena of dark states and electromagnetically induced transparency ~EIT! have greatly enriched the fields of nonlinear and quantum optics in recent years. Although these two processes produce similar effects, they have important distinctions. Atomic dark states @1,2# are coherent superpositions of the two lower levels in a threelevel lambda (L) system that are not coupled...
متن کاملElectromagnetically Induced Transparency in 6 Li Electromagnetically Induced Transparency In
We report electromagnetically induced transparency for the D1 and D2 lines in 6 Li in both a vapour cell and an atomic beam. Electromagnetically induced transparency is created using co-propagating mutually coherent laser beams with a frequency difference equal to the hyperfine ground state splitting of 228.2 MHz. The effects of various optical polarization configurations and applied magnetic f...
متن کاملObservation of electromagnetically induced transparency and slow light in the dark state--bright state basis.
The quantum coherence phenomenon of electromagnetically induced transparency (EIT) is observed in a three-level system composed of an excited state and two coherent superpositions of the two ground-state levels. This peculiar ground state basis is composed of the so-called bright and dark states of the same atomic system in a standard coherent population trapping configuration. The characterist...
متن کاملElectromagnetically induced transparency
The subject of electromagnetically induced transparency (EIT) is reviewed in this paper. Emphasis is placed on the experimental work reported in this ®eld since 1990. Theoretical work is also covered, although it is not intended to review all the very numerous recent theoretical treatments on this topic. The basic physical ideas behind EIT are elucidated. The relation of EIT to other processes ...
