We present an overview of nonlinear phenomena related to optical quadratic solitons—
intrinsically multi-component localized states of light, which can exist in media without …

We review publications on transverse dynamics in cavity nonlinear optics during the years
2000–2003. Topics covered are transverse pattern dynamics, localized structures, scaling of …

The growth of regularity from disorder, the evolution from the simple towards the complex,
and the spontaneous formation of spatio temporal patterns in general are questions which …

We identify a universal criterion for the onset of a nonequilibrium Ising-Bloch (NIB) transition,
and describe the behavior near the bifurcation by a generic amplitude equation. We found …

Stability domains (ie, pump frequency detuning range) of a single dark soliton (or platicon)
and dark breather in high-Q Kerr optical microresonators with normal group velocity …

We have observed transverse pattern formation in type-II continuous-wave triply resonant
optical parametric oscillators (OPOs). Different kinds of cavities with degenerate transverse …

We discuss the existence and the stability properties of spatial solitons, which are excited in
externally driven nonlinear resonators. First, we give a short derivation of the basic …

We report the controlled observation of the nonequilibrium Ising-Bloch transition in a broad
area nonlinear optical cavity (a quasi-1D single longitudinal-mode photorefractive oscillator …

Many dissipative optical systems support patterns. Dissipative solitons are generally found
where a pattern coexists with a stable unpatterned state. We consider such phenomena in …

Spatially localized oscillations in periodically forced systems are intriguing phenomena.
They may occur in spatially homogeneous media (oscillons), but quite often emerge in …
