Dissipative surface solitons in periodic structures

Modulational instability and solitons in a periodic dissipative feedback system

We review our recent experimental results on control of the modulational instability, pattern formation, and solitons in a nonlinear discrete dissipative feedback system. We show that the discreetness and bandgap effects can provide efficient control of the nonlinear instability modes of the system. Furthermore, we explore the possibilities for excitation of dissipative discrete solitons in suc...

Magnetic field induced transient periodic dissipative structures in nematics

The lJnearized version of nonstochastic cont~nuum theory is used wJth the ngid anchonng hypothesis to study the occurrence of transient penodic dissipative structures (DS) induced m a nematic sample by a magnetic field H of supercritical strength applied m a

Dissipative solitons and antisolitons

Using the method of moments for dissipative optical solitons, we show that there are two disjoint sets of fixed points. These correspond to stationary solitons of the complex cubic–quintic Ginzburg–Landau equation with concave and convex phase profiles respectively. Numerical simulations confirm the predictions of the method of moments for the existence of two types of solutions which we call s...

Midband dissipative spatial solitons.

We show dissipative spatial solitons in nonlinear optical microresonators in which the refractive index is laterally modulated. In addition to "normal" and "staggered" dissipative solitons, similar to those in spatially modulated conservative systems, a narrow "midband" soliton is shown, having no counterparts in conservative systems.
