The current research into solitons and their use in fiber optic communications is very important to the future of communications. Since the advent of computer networking and …
Ultrashort pulse propagation in high gain optical fiber amplifiers with normal dispersion is studied by self-similarity analysis of the nonlinear Schrödinger equation with gain. An exact …
A broad class of exact self-similar solutions to the nonlinear Schrödinger equation (NLSE) with distributed dispersion, nonlinearity, and gain or loss has been found. Appropriate …
Pulse propagation in high-gain optical fiber amplifiers with normal group-velocity dispersion has been studied by self-similarity analysis of the nonlinear Schrödinger equation with gain …
Self-similarity techniques are used to study pulse propagation in a normal-dispersion optical fiber amplifier with an arbitrary longitudinal gain profile. Analysis of the nonlinear …
We show analytically that bright and dark spatial self-similar waves can propagate in graded- index amplifiers exhibiting self-focusing or self-defocusing Kerr nonlinearities. The intensity …
A broad class of exact self-similar solutions to the nonlinear Schrödinger equation (NLSE) with distributed dispersion, nonlinearity, and gain or loss has been found describing both …
Isotope shifts in the nuclear charge radius of even and odd calcium isotopes are calculated within the nuclear shell model. The model space includes all configurations of nucleons in …
We report the observation of self-trapping of light in a self-written channel in a photosensitive glass waveguide. As the refractive index changes induced in the glass are permanent, the …
