Detuned Electromagnetically Induced Transparency in N -type Atom System
نویسنده
چکیده
The electromagnetically induced transparency (EIT) in an N configuration is studied under both resonant and off-resonant conditions. In a certain off-resonant condition the dark state of the four level system, which is almost the same as the resonant dark state in Λ configuration, is rebuilt. The actual system with damping is examined using optical Bloch equation, both numerically and analytically. Based on this detuned dark state, some new applications with frequency shifts can be realized.

Double Electromagnetically Induced Transparency in a Tripod-type Atom System
The electromagnetically induced transparency (EIT) phenomenon in a four level atomic system with tripod configuration is studied. The results show that this configuration is equivalent to the combination of two single three-level Λ configurations, which, under certain conditions, results in the so-called double-EIT (DEIT) phenomenon. The properties of the double transparency windows for DEIT ar...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...

Dissipation-free photon-photon interactions at the single photon level is studied in the context of cavity electromagnetically induced transparency (EIT). For single atoms in the strong coupling regime exhibiting EIT, photon-photon interaction is bounded above by the single atom-photon coupling strength. Photon blockade and antibunching occur for both single and multi-atom cases. It is shown th...

In this paper, we present a method to generate continuous-variable-type entangled states between photons and atoms in atomic Bose-Einstein condensate (BEC). The proposed method involves an atomic BEC with three internal states, a weak quantized probe laser and a strong classical coupling laser, which form a three-level Λ-shaped BEC system. We consider a situation where the BEC is in electromagn...
متن کاملSlow light propagation and amplification via electromagnetically induced transparency and four-wave mixing in an optically dense atomic vapor
We experimentally and theoretically analyze the propagation of weak-signal field pulses under the conditions of electromagnetically induced transparency (EIT) in hot Rb vapor, and study the effects of resonant four-wave mixing (FWM). In particular, we demonstrate that in a doublesystem, formed by the strong control field with the weak resonant signal and a far-detuned Stokes field, both continu...
