Non-Hermitian electronics multipods of electromagnetically induced transparency (EIT) and absorption (EIA)

چکیده
We study a non-Hermitian electronic dimers system based on an imaginary resistor (Z) in (N + 2) level atomic multipod configuration. Non-Hermitian systems depend gain/loss parameter and are specifically marked by degeneracy exhibited at exceptional point separating different phases of complex modes dynamics. Interestingly, the structural characterization dispersive properties reveal broad range strong coupling where interplay between control probe field induce simultaneous EIT, EIA ATS. Here, identifying underlying physical mechanisms, we show that multiple windows transparency can be strongly enhanced incorporation several network. On other hand, if pumping is resonant weak regime, EIT result number dimers. Remarkably, proposed embedded mechanism whose modulation induces couplingless (CPLP) whereby energy cross. At this related phenomena vanish.

Controlling 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 کاملSlow Light by Electromagnetically Induced Transparency ( EIT ) in Semiconductors
The ability to controllably slow down the propagation of light pulses can enable a variety of important applications. In recent years, two different approaches have been pursued for slow light. One approach explores dispersion engineering with passive optical elements such as resonators, filters, and photonic bandgap structures. The other approach takes advantage of coherent nonlinear optical p...

متن کاملSwitching from "absorption within transparency" to "transparency within transparency" in an electromagnetically induced absorption dominated transition.
The absorption of a resonant coupling laser driving a closed degenerate two-level system in an atomic cesium beam was investigated as a function of the detuning of a second laser probing the same transition. The measurements were performed for four different polarization combinations of the two laser beams. Except for the beams of counterrotating polarizations all coupling-laser absorption prof...
