Nonvolatile optical memory via recoil-induced resonance in a pure two-level system
A. J. F. de Almeida, M. -A. Maynard, C. Banerjee +3
We report on the storage of light via the phenomenon of recoil-induced resonance in a pure two- level system of cold cesium atoms. We use a strong coupling beam and a weak probe be…
Narrow band amplification of light carrying orbital angular momentum
G. C. Borba, S. Barreiro, L. Pruvost +2
We report on the amplification of an optical vortex beam carrying orbital angular momentum via induced narrow Raman gain in an ensemble of cold cesium atoms. A 20\% single-pass Ram…
Zero-area single photon pulses
L. S. Costanzo, A. S. Coelho, D. Pellegrino +6
Broadband single photons are usually considered not to couple efficiently to atomic gases because of the large mismatch in bandwidth. Contrary to this intuitive picture, here we de…
Power-Broadening-Free Correlation Spectroscopy in Cold Atoms
H. M. Florez, L. S. Cruz, M. H. G. de Miranda +4
We report a detailed investigation on the properties of correlation spectra for cold atoms under the condition of Electromagnetically Induced Transparency (EIT). We describe the tr…
Pulse pair generation from coherently prepared atomic ensembles
D. Moretti, D. Felinto, J. W. R. Tabosa
We report a detailed investigation on the generation of pulse pairs during the readout of a coherence grating stored in a cold atomic ensemble. The pulse shapes and the split of th…
Functional Quantum Nodes for Entanglement Distribution over Scalable Quantum Networks
Chin-Wen Chou, Julien Laurat, Hui Deng +4
We demonstrate entanglement distribution between two remote quantum nodes located 3 meters apart. This distribution involves the asynchronous preparation of two pairs of atomic mem…
