“…To make a comparison, we display the static reflection and transmission signals versus Δ 3 and L. First, when the E 2 laser beam is blocked, according to the expressions of R s and T s in Eqs. (6) and 7, we can obtain the SWM BGS, PTS, and PBG structure as shown in Figs. 6(a1)-6(d1).…”

“…Over the past few decades, a lot of attention has been paid to the electromagnetically induced transparency (EIT) [1,2] in atoms. The nonlinear optical effect, four-wave mixing (FWM) [3], which can be enhanced or suppressed [4][5][6] in an EIT medium, is well known. The electromagnetically induced grating (EIG) [7,8,9] that results from two counterpropagating coupling fields [10,11] is reported in a variety of interesting research results [12][13][14].…”

For the first time, to the best of our knowledge, we investigate the photonic band gap (PBG) structure through scanning the frequency detunings of the probe field, the dressing field, and the coupling field in the static and moving electromagnetically induced grating (EIG) field. When we scan the frequency detuning of the coupling field, the PBG structure and six-wave-mixing band gap signal (SWM BGS) appear at the right of the electromagnetically induced transparency (EIT) position. But the PBG structure and SWM BGS appear at the left of the EIT position in the case of scanning the probe field frequency detuning. Also, on the condition of scanning the probe field frequency detuning, the SWM BGS appears in two frequency ranges. Moreover, in the moving PBG structure, nonreciprocity of the SWM BGS can be obtained. Furthermore, the intensity, width, and location of the SWM BGS can be modulated through changing the frequency detunings and intensities of the probe field, the dressing field, and the coupling field; the sample length; and the frequency difference of coupling fields in EIG. Such a scheme could have potential applications in optical diodes, amplifiers, and quantum information processing.

“…In order to explain the SP-FWM signals specifically, the two weak fields E as and E s are evolved into the Hamiltonian system when they propagate in the nonlinear medium. The measured intensities of output signals are proportional to the photon numbers, which are given by [24] hN s i Ω − 1m∕n;…”

We mainly investigate four generated four-wave-mixing (FWM) signals, and second-and fourth-order fluorescence (FL) signals, simultaneously in a cascade three-level atomic system of sodium, in which dual electromagnetically induced transparency windows are used to enable transparency of the generated FWM signals. The moving and immobile two-photon dressing effects on the FWM and multi-order FL signals as well as the interaction of dressing effects are studied. Furthermore, we investigate the spontaneous parametric FWM signal and spatial images of the transmitted probe signal modulated by the cross-Kerr nonlinearities effect of the dressing field both experimentally and theoretically. The study may find applications in all-optical communication.

“…It is well-known that the six-wave mixing (SWM) is a nonlinear optical effect generated by lights with different frequencies and different quantum properties. In the nonlinear wave-mixing process, atomic coherence of the electromagnetically induced transparency (EIT) plays a critical role has been demonstrated experimentally and theoretically in recent researches [4][5][6][7][8][9]. Furthermore, the increasingly effect has been paid on the switch between EIT and electromagnetically induced absorption (EIA) [3,10].…”

For the first time, we experimentally and theoretically research about the second-order nonlinear signal (SNS) including electromagnetically induced absorbing (EIA) and electromagnetically induced gain (EIG), six wave mixing band gap signal (SWM BGS) resulting from photonic band gap structure in an inverted Y-type four level system with the electromagnetically induced grating. The interplay between the SNS and SWM BGS is illustrated clearly for the first time. When we change the frequency detuning to make the SWM BGS and SNS overlap, the SWM BGS is suppressed and the intensity of SNS is strongest near the resonance point. We can control the intensity of the SWM BGS and EIG caused by the classic effect through changing the power of coupling field. And the changes on the EIA generated by the quantum effect are obtained by changing the power of dressing field. Since the SWM BGS is the enhancement of the four wave mixing band gap signal (FWM BGS), when we set FWM BGS as the input and SNS as the modulation role to control the amplification amplitude for the FWM BGS in our scheme, the adjustable optical amplifier can be obtained.
