“…A comprehensive review on optical quadratic solitons was published by Buryak, Di Trapani, Skryabin, and Trillo [2002], and can be also found in a recent book by Kivshar and Agrawal [2003]. A number of overview papers on the theory and experimental generation of spatial parametric optical solitons in quadratic nonlinear media were published during the last years (Stegeman, Schiek, and Fuerst [1997]; Kivshar [1997]; Torner [1998]; Etrich, Lederer, Malomed, Peschel, and Peschel [2000]; Stegeman [2001]; Sukhorukov [2001]; Torruellas, Kivshar, and Stegeman [2001]), and summaries of the advances in the field were reported by ; Stegeman [1999]; Torner and Stegeman [2001]; Torner and Sukhorukov [2002]; Torner and Barthelemy [2003].…”

Optical vortices and vortex solitons

Optical vortices are phase singularities nested in electromagnetic waves that constitute a fascinating source of phenomena in the physics of light and display deep similarities to their close relatives, quantized vortices in superfluids and Bose-Einstein condensates. We present a brief overview of the major advances in the study of optical vortices in different types of nonlinear media, with emphasis on the properties of vortex solitons. Self-focusing nonlinearity leads, in general, to the azimuthal instability of a vortex-carrying beam, but it can also support novel types of stable or meta-stable self-trapped beams carrying nonzero angular momentum, such as ring-like solitons, necklace beams, and soliton clusters. We describe vortex solitons created by multi-component beams, by parametrically coupled beams in quadratic nonlinear media, and in partially incoherent light, as well as discrete vortex solitons in periodic photonic lattices.
