We provide an overview of recent experimental and theoretical developments in the area of optical discrete solitons. By nature, discrete solitons represent self-trapped wavepackets in nonlinear periodic structures and result from the interplay betwee

Quadratic spatial solitons

Autor: George I. Stegeman

Publikováno v: Comptes Rendus Physique. 8:221-233

Quadratic spatial solitons, beams that propagate unchanged in shape and magnitude, are supported by second order optical nonlinearities and can occur in all wave mixing processes under appropriate conditions. They are multi-component, consisting of a

Publikováno v: Laser Physics. 16:902-910

The Raman effect, by which light is frequency shifted by a vibrational mode, enters into a number of phenomena in nonlinear optics. Here, we summarize our progress in identifying glass materials with potentially useful Raman properties, methods for m

Optical spatial solitons: historical perspectives

Autor: George I. Stegeman, D. N. Christodoulides, Mordechai Segev

Publikováno v: IEEE Journal of Selected Topics in Quantum Electronics. 6:1419-1427

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 displaying properties that are normally associated with real particle
