Modulational instability of bright solitary waves in incoherently coupled nonlinear Schrödinger equations.

We present a detailed analysis of the modulational instability (MI) of ground-state bright solitary solutions of two incoherently coupled nonlinear Schrödinger equations. Varying the relative strength of cross-phase and self-phase effects we show the existence and origin of four branches of MI of the two-wave solitary solutions. We give a physical interpretation of our results in terms of the g...

Modulational instability of optical beams in photorefractive media in the presence of two wave and four wave mixing effects

Modulational instability in a photorefractive medium is studied in the presence of two wave mixing. We then propose and derive a model for forward four wave mixing in the photorefractive medium and investigate the modulational instability induced by four wave mixing effects. By using the standard linear stability analysis the instability gain is obtained. In both the cases, the geometry is such...

On the Instability of Solitary-wave Solutions for Fifth-order Water Wave Models

This work presents new results about the instability of solitarywave solutions to a generalized fifth-order Korteweg-deVries equation of the form ut + uxxxxx + buxxx = (G(u, ux, uxx))x, where G(q, r, s) = Fq(q, r) − rFqr(q, r) − sFrr(q, r) for some F (q, r) which is homogeneous of degree p+ 1 for some p > 1. This model arises, for example, in the mathematical description of phenomena in water w...

Neck instability of bright solitary waves in hyperbolic Kerr media

Symmetry-breaking instability of solitons has been studied in different areas of physics and appears as a common feature shared by most solitons despite the diversity of the physical systems that support them [1–3]. In optics, the break-up of self guided light beams through transverse and/or modulational instability has been demonstrated for solitons in self-focussing and defocusing Kerr media ...
