Physical Significances Of Fifth-Order Nonlinearity For Pulse Dynamics In Monomode Optical Fibres
نویسندگان
چکیده
We discuss, with illustrations, some physical significances of fifth-order nonlinear susceptibility for pulse dynamics in monomode optical fibres. The amplitude dynamic governing equation is the cubic-quintic nonlinear Schrödinger equation, (CQNLSE), which has soliton properties similar to the cubic nonlinear Schrödinger equation, (CNLSE), based on solutions by a variational method. Some differences, with regards to pulse durations in the range from 10 picoseconds to a few femtoseconds that make CQNLSE experimentally more viable are explained. PACS: 42.81.Dp; 42.65.Tg; 42.81.Wg; 42.81.-i

Symmetrical dispersion compensation for standard monomode-fiber-based communication systems with large amplifier spacing.
Optical 10-Gbit / s return-to-zero pulse transmission in cascaded communication systems using dispersion compensation of the standard monomode fiber with large amplifier spacing is examined. It is shown that pulse distortions that are due to Kerr nonlinearity are significantly diminished by symmetrical ordering of the compensation sections when the total number of precompensation and postcompen...

We argue that the integrable modified nonlinear Schrödinger equation with the nonlinearity dispersion term is the true starting point to analytically describe subpicosecond pulse dynamics in monomode fibers. Contrary to the known assertions, solitons of this equation are free of self-steepening and the breather formation is possible.
متن کاملDynamics of Dark Solitons
-Spatial dark solitons are known to be stable nonlinear localized waves in self-defocusing media. We demonstrate how to analyse the dynamics of dark solitons in the presence of small perturbations, and we consider the effect of two-photon absorption on dark solitons as a particular example. We also predict a new type of dark solitons of circular symmetry, ring dark solitons, which are stable ag...
