A coherent atomic medium is proposed for manipulating the absorption, dispersion, transmission and reflection of an optical soliton via two strong coherent control field's Rabi oscillations, detunings and incident angles. Significant anomalous dispersion regions and a negative group index are investigated. A group index of n g =−1500 and a negative group velocity of v g =−2.0×10 5 ms −1 is calculated. This leads to superluminal propagation (v g >c) in the anomalous dispersion region. A significant cancellation of linear and nonlinear effects results a bright optical soliton in the coherent atomic medium. Similarly the shape-preserving phenomenon of the bright optical solitons is investigated by launching the input pulse at different incident angles. As a result, the intensity distribution of the optical solitons has no fluctuation in time t/τ 0 with any values of y/ω 0 and shows a significant bright form of solitary waves. These solitons show remarkable applications in optics, particularly in soliton radar technology for medical purposes, controlling the intensity of bright solitons for the modification of optical information processing, high-speed optical switching and quantum communication.

The dielectric tensor of four level atomic medium coupled with dielectric function of silver silica nano-composites material to modify dispersion relation of surface plasmon polaritons (SPPs). The rapid damping of SPPs is used to localized atomic particles in two dimension inverse position space. Directions, phases and intensity of the control field play important roles in the localization of atoms in a unit wavelength domain. Ten, six, four and two localization peaks are investigated by SPPs damping in different quadrants. A single broad localized peak symmetric about origin are also investigated. The theoretical work of this article may be useful for quantum information in Plasmonster technology.

The birefringence characteristics of reflection and transmission of light pulse are explored in chiral medium driving by two probe electric and magnetic fields, while four control fields. The proposed medium show significant birefringence behaviors in reflection/transmission and Goos-Hänchen (GH) shifted beams. The birefringent GH-reflected and GH-transmitted pulses show significant contribution in the space time gap creation for secure communication and invisibility. A space-time gap has been observed in the reflection, transmission and corresponding GH-shifted reflection and transmission birefringent beams. The theoretical results may be useful for noise free secure communication in invisible radar technology.
