Electromagnetically induced spatial nonlinear dispersion of four-wave mixing
نویسندگان
چکیده
Spatial displacements of the probe and generated four-wave mixing beams are observed in a three-level V-type, as well as a two-level atomic system near resonance. The observed spatial shift curves reflect the typical enhanced cross-Kerr nonlinear dispersion properties in the electromagnetically induced transparency EIT systems. The spatial beam displacements are controlled by the strong control laser beam and the atomic density. Studying such controlled spatial beam shifts can be important in image storage and in generating spatially correlated entangled laser beams in multilevel EIT systems.

Observations of Autler-Townes spatial splitting of four-wave mixing image
We report the selfand external-dressed AutlerTownes (A-T) splittings of the images of the generated four-wave mixing signal (FWM) and electromagnetically induced transparency (EIT) of probe images in cascade three-level atomic system. Such spatial properties of probe and FWM signals are induced by the enhanced cross-Kerr nonlinearity. We demonstrate the controlled electromagnetically induced sp...
متن کاملFour-wave-mixing stopped light in hot atomic rubidium vapour
Digital signal processing, holography, and quantum and classical information processing rely heavily upon recording the amplitude and phase of coherent optical signals. One method for achieving coherent information storage makes use of electromagnetically induced transparency. Storage is achieved by compressing the optical pulse using the steep dispersion of the electromagnetically induced tran...
متن کاملCoupled atomic coherences induced by a standing wave
Atomic coherence effects with a strong standing-wave coupling field on a four-level system of hot Rb atoms are investigated. Amplitude modulation and phase modulation of the strong standing-wave field are coherently coupled in linear and nonlinear atomic polarizations in various multi-wave mixing processes. Such coupled atomic coherence effect leads to one-photon triple-bandpass filters in an e...
متن کاملOpening four-wave mixing and six-wave mixing channels via dual electromagnetically induced transparency windows.
Highly efficient four-wave mixing (FWM) and six-wave mixing (SWM) processes can coexist in a four-level Y-type atomic system due to atomic coherence. The simultaneously opened dual electromagnetically induced transparency windows in this four-level atomic system allow observation of these two nonlinear optical processes at the same time, which enables detailed studies of the interplay between t...
متن کاملTemporal and Spatial Interference between Four-Wave Mixing and Six-Wave Mixing Channels.
Using phase control between four-wave mixing (FWM) and six-wave mixing (SWM) channels in a four-level atomic system, we demonstrate temporal and spatial interferences between these two nonlinear optical processes. Efficient and coexisting FWM and SWM signals are produced in the same electromagnetically induced transparency window via atomic coherence. The temporal interference has a femtosecond...
