Storage and Retrieval of an Image using Four-Wave Mixing in a Cold Atomic Ensemble
Storage Retrieval of an Image Four-Wave Mixing Cold Atomic Ensemble
2012/4/19
We experimentally realized storage and retrieval of an image of light in a cigar-shaped atomic cloud of Rubidium 85 using four-wave mixing (FWM) for the first time. The input signal and the generated ...
Coherent manipulation of spin wave vector for polarization of photons in an atomic ensemble
spin wave vector Coherent manipulation polarization of photons atomic ensemble
2011/8/3
Abstract: We experimentally demonstrate the manipulation of two-orthogonal components of a spin wave in an atomic ensemble. Based on Raman two-photon transition and Larmor spin precession induced by m...
We present measurements of the cross-correlation function of photon pairs at 780 nm and 1367 nm, generated in a hot rubidium vapor cell. The temporal character of the biphoton is determined by the di...
Observation of prolonged coherence time of the collective spin wave of atomic ensemble in a paraffin coated Rb vapor cell
prolonged coherence collective spin wave atomic paraffin coated Rb vapor cell
2010/4/9
We report a prolonged coherence time of the collective spin wave of a thermal 87Rb atomic ensemble in a paraffin coated cell. The spin wave is prepared through a stimulated Raman Process. The long coh...
Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble
Collapses orbital angular momentum light atomic ensemble
2010/4/8
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coher...
