Solitons that have carrier waves are classified as envelope solitons. the dark soliton trains were formed from highly dispersive dipole-exchange SW propagated in a thin YIG film at frequencies situated near the dipole gaps.

The goal was to investigate phenomena associated with the cascading of second order nonlinear optical processes and identify potential applications.

6-1-1992 · Propagation of light waves in a thin, self-defocusing, nonlinear film bounded by an infinite self-defocusing medium of a different nonlinearity is investigated. It is shown that both gray and dark solitary waves can be trapped in the film when the linear refractive index of the film, nf, is smaller than that of the cladding, no, and These heterogeneities depend on the experimental conditions of a deposition process being used. They have essential influence on practical properties of thin films and their modeling is important for achieving further progress in thin film optical technology. The presented …

Effects of low-intensity UV treatment on the optical constants of red BS dye-doped polymethyl methacrylate (PMMA) film including refractive index, extinction coefficient, real and imaginary parts of dielectric constant, band gap energy, Urbach energy, and refractive index dispersion parameters are measured and calculated. We consider two-dimensional stationary solitary pulses in a falling film by using the two-dimensional generalized Kuramoto-Sivashinsky equation as a model system. We numerically construct solitary wave solutions of this equation as a function of the dispersion parameter. We obtain an analytical estimate for the speed of these waves in the

In particular, we describe multi-channel solitary waves in bit-parallel-wavelength fiber transmission systems for high-performance computer networks, multi-color parametric spatial solitary waves due to cascaded nonlinearities of quadratic materials, and quasiperiodic envelope solitons due to quasi-phase-matching in Fibonacci optical superlattices.

Abstract We analyze interaction of two nonlinear waves in thin amorphous dielectric film with reflecting edges. All-optical logic gates “AND”, “OR” and “XOR”, which are based on the dielectric film and involve no semiconductor components, are simulated both analytically and numerically. 4-3-2014 · Our results show that surface waves, consisting of large horseshoe-shaped wave humps concentrating most of the liquid and preceded by capillary ripples on a thin residual film, segregate the flow field into two regions: an inertia-dominated one in the large humps, where the local Reynolds number is up to five times larger than its mean value
