Spatial optical solitons supported by mutual focusing

Opt Lett. 2003 Aug 15;28(16):1457-9. doi: 10.1364/ol.28.001457.

Abstract

We study composite spatial optical solitons supported by two-wave mutual focusing induced by cross-phase modulation in Kerr-like nonlinear media. We find the families of both single- and two-hump solitons and discuss their properties and stability. We also reveal remarkable similarities between recently predicted holographic solitons in photorefractive media and parametric solitons in quadratic nonlinear crystals.
