It is almost common knowledge now that particles also possess properties of waves. But,
can localized wave-packets behave and interact like particles? This article is dedicated to …

Optical spatial solitons are self-trapped optical beams that exist by virtue of the balance
between diffraction and nonlinearity. They propagate and interact with one another while …

Solitons, nonlinear self-trapped wavepackets, have been extensively studied in many and
diverse branches of physics such as optics, plasmas, condensed matter physics, fluid …

A generalization of self-guided beams (spatial solitons) is discussed. Each beam is
characterized by an axially uniform intensity profile whose polarization state changes with …

We formulate the theory describing the evolution and interactions between optical spatial
solitons that propagate in opposite directions. We show that coherent collisions between …

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 …

The possible forms the intensity dependence of the nonlinear refractive index would have to
take for bistable light bullets to exist are examined. Bistable light bullets are propagating …

The issues involved in the production of light pulses and the progress made towards their
experimental realization are discussed. The possibility of creating and observing …

This article serves as an introduction to the focus issue on optical solitons. After a short
review of the history of solitons and the field of integrable systems, a brief overview of the …

Spatial optical solitons may provide a powerful means for creating reconfigurable, all-optical
circuits in which light is guided and controlled by light. We present a panoramic overview of …
