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...
متن کاملDouble 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...
متن کاملThe Effect of Antenna Movement and Material Properties on Electromagnetically Induced Transparency in a Two-Dimensional Metamaterials
Increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (EIT) and similar phenomena i...
متن کاملDetuned Electromagnetically Induced Transparency in N -type Atom System
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 analytica...
