“…When the perturbing laser copropagates with the probe laser, there are six (CHB) and two (EIT) that can be observed in a Doppler-broadened four level N-type atomic system by adjusting the perturbing Rabi frequency or the saturating detuning [30] . In previous reports [31][32][33] , we presented the Doppler broadened of the imaginary part of the susceptibility of probe field which represent the absorption spectrum for the four-level N-type atomic system, we displayed a number of effects for the spectra behavior, the appearance of zero absorption points, controllability of EIT and EIA and also the spectral holes can be enhanced strongly by means of the transverse dependence of the electromagnetic fields in a Doppler broadened medium and presence of SGC. All the results are observed without including numerous hyperfine levels and Zeeman sublevels to the atomic system.…”

We study the polarization properties theoretically in a Doppler broadened N-type four-level atomic system under the effect of a strong-probe field. We calculate the polarization coherence of a system at exact analytical solution. The coherent holes are observed and controlled by adjusting the parameters of spontaneously generated coherence (SGC), transverse fields, the Doppler width and coherent coupling fields as well as the nonradiative decay rates. The three-dimension of the spectra are plotted to observe the coherent holes clearly when the probe polarization spectrum depends explicitly on the nonradiative decay rates.

“…Wu et al [27] investigated the coherent hole-burning phenomenon in a three-level Λ-type configuration using the technique of Doppler broadening and the existence of saturating and coupling laser fields. Further, Elnabi [28] has reported coherent hole burning in a four-level N-type atomic configuration without using a saturation field in a Doppler broadened system.…”

We investigate the possibility of creating spectral hole burning in surface plasmon polaritons (SPPs) at the interface of sodium vapor and gold media. The spectral holes are measured at specific parameters, phases and directions of the control fields. The direction and phase of the control field affect the creation of spectral hole burning in SPPs the most. The pulse shape in the spectral burning hole region is uniform and undistorted due to the cancellation of nonlinear Doppler broadening and large group velocity dispersion. The behavior of SPPs pulse in the spectral hole region is that of solitons, which arise due to cancellation of large positive dispersion for phase shift with nonlinear effect.. The results may have potential applications in nano-photonics, plasmonsters, photovoltaic devices, cloaking and sensing technology.

Spectral hole burning is investigated in an optical medium in the presence of Doppler broadening and Kerr nonlinearity. The Kerr nonlinearity generates coherent hole burning in the absorption spectrum. The higher order Kerr nonlinearity enhances the typical lamb dip of the hole. Normal dispersion in the hole burning region while Steep anomalous dispersion between the two hole burning regions also enhances with higher order Kerr effect. A large phase shift creates large delay or advancement in the pulse propagation while no distortion is observed in the pulse. These results provide significant steps to improve optical memory, telecom devices, preservation of information and image quality.
