This paper studies solitons in optical metamaterials by the aid of collective variables. As an assumption, super-Gaussian solitons are selected to keep these pulses on a generalized setting. The numerical simulations of soliton parameter variation are given for specific values of the superGaussian pulse parameters.

This paper presents collective variable approach for super-sech soliton dynamics in optical metamaterials. The soliton dynamics is governed by the generalized nonlinear Schrödinger's equation. The numerical simulations of pulse width, amplitude, chirp and frequency are given.

In this paper, we investigate broadband supercontinuum generation in photonic crystal fibers using cosh-Gaussian optical pulses, which provide flatter spectrum than standard Gaussian pulses. This fact can be crucial for telecommunication systems applications. The intensive numerical study of three main telecommunication windows pointed out the most prominent window for spectral broadening. This finding offers the possibility of improving the characteristics of multi-wavelength sources and to enable wavelength density multiplexing systems.
