Resumen
We study the effect of Kerr type nonlinear medium in quantum state transfer (QST). We have investigated the effect of different coupling schemes and Kerr medium parameters [Formula: see text] and [Formula: see text]. We found that the Kerr medium introduced in the connection channel can act like a controller for QST. The numerical simulations are performed without taking the adiabatic approximation. Rotating wave approximation is used in the atom–cavity interaction only in the lower coupling regime.

Resumen
Abstract The advent of silica-based low-cost standard single-mode fibers revolutionized the whole communication industry. The deployment of optical fibers in the networks induces a paradigm shift in the communication technologies used for long-haul information transfer. However, the communication using the optical fibers is affected by several linear and nonlinear effects. The most common linear effects are attenuation and chromatic dispersion, whereas the dominant nonlinear effect is the Kerr effect. The Kerr effect induces a power-dependent nonlinear distortion for the signal propagating in

Resumen
<em>The need for high data rates and bandwidth has resulted in communicating via optical fibers. A couple of undesirable nonlinear effects in the optical fiber medium has become a factor of noticeable concern at high power levels. These fiber nonlinearities introduce errors into the transmitted data stream transported over optical fiber communication systems. Information carried by a light signal in a Wavelength Division Multiplexing (WDM) system is subject to degradation due to nonlinear effects in the fiber. Under the influence of intense electromagnetic field, any dielectric medium shows no

Resumen
The applied method of slowly varying amplitudes gives us the possibility to reduce the nonlinear vector integrodifferential wave equation of the electrical and magnetic vector fields to the amplitude vector nonlinear differential equations. Using this approximation, different orders of dispersion of the linear and nonlinear susceptibility can be estimated. Critical values of parameters to observe different linear and nonlinear effects are determined. The obtained amplitude equations are a vector version of3D+1nonlinear Schrödinger equation (VNSE) describing the evolution of slowly varying ampl

Producing few-cycle light pulses with a sufficient intensity to observe these phenomena has only become possible with the recent development of mode-locked lasers.

Resumen
Abstract The investigation of magneto-optical effects is historically rooted in the early part of the nineteenth century when physicists started to search for relationships between various natural phenomena. Magneto-optical searches date back to 1812 when Domenico Morichini of Rome erroneously claimed that steel needles could be magnetized utilizing violet radiation in the solar spectrum. A null result was reported circa 1825, when Sir John Herschel examined the propagation of a beam of polarized light along the axis of a helix carrying an electric current.

This chapter addresses the effects of higher-order Raman scattering on modulational instability in optical fibers with pure-quartic dispersion. Low- and high-input power regimes are affected by self-frequency shift (SFS) effects and, due to the presence of the quintic nonlinearity and quartic dispersion, this leads to extended zones of instability in the gain spectrum. Here, we demonstrate via numerical simulations that our biharmonic nonlinear Schrödinger (NLS) equation exhibits ultrashort pulse trains, including rogue wave (RW)-like patterns, as well as trains of Akhmediev breathers (ABs).
