Abstract: We report the control of the dressed state in three-mode optical entanglement in an N-type four-level system using two cascaded parametric amplification four-wave mixing steps inside an atom-like optical cavity and injected by thermal optical fields: a coherent field and the Einstein–Podolsky–Rosen field. First, cavity dressing results in Aulter–Towns-like (AT-like peak) anti-squeezing. And the three-cavity dressing interaction induces multi-AT-like peaks. Meanwhile, the cavity enhanced nonlinear gain results in one squeezing dip polariton. In addition, the coupling of three enhanced nonlinear gains brings about multi-dip squeezing. Second, as two nonlinear coefficients change, the nonlinear phase makes the squeezing profile (in phase, amplification) turn into an anti-squeezing profile due to nonlinear loss (out of phase, de-amplification). Finally, the squeezing profile can also be modified by field dressing (AT splitting, enhancement and suppression), and the squeezing degree is affected by injection fields. Thus, by judging the squeezing of three nonseparability criteria, we get three-mode optical entanglement.

TL;DR: In this paper, the authors have demonstrated the switching from two-mode bunching to anti-bunching like phenomenon of noise intensity fluctuations used for noise correlation, where switching in bunching phenomenon is caused by relative nonlinear phase, which is induced by self-and cross-phase modulation.

TL;DR: In this article, a theoretical study about the two-and three-mode intensity-difference squeezing inside an atom-like optical cavity was performed using a cascaded parametric amplification four-wave mixing (PA-FWM) process, and the cavity dressing and "dressing-like" effects with different nonlinear coefficients affecting the degree of squeezing of the fluctuation spectra were investigated.

TL;DR: In this paper, the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments.
Electromagnetically Induced Transparency
TL;DR: Electromagnetic induced transparency is a technique for eliminating the effect of a medium on a propagating beam of electromagnetic radiation EIT may also be used, but under more limited conditions, to eliminate optical self-focusing and defocusing and to improve the transmission of laser beams through inhomogeneous refracting gases and metal vapors, as figure 1 illustrates.
