Formation and interaction of spatially incoherent solitons in a slow nonlinear medium

Abstract

Spatial soliton represents an optical beam propagating in nonlinear medium without changing its shape. Spatial soliton has been associated with coherent optical beam. The unique structure of incoherent solitons is also reflected in their collisional properties. The interaction of the multicomponent incoherent solitons in photorefractive SBN crystals was studied. It was found that these solitons change their profile in collision. However, since the photorefractive nonlinearity is of saturable character, the soliton collisions are inelastic. Consequently, the solitons have oscillatory dynamics after the collision. Show more
