Bragg diffraction of colliding spatial photorefractive solitons in SBN

摘要

The use of spatial solitons to effect optical interconnects is being actively studies by a number of researchers. Perhaps unjustifiably overlooked in this work is the formation of a rrating where two solitons intersect, and the diversion of light into a new path through the resulting Bragg diffraction. An experiment is conducted in which solitons, formed from two mutually coherent argon beams, collide at an angle of several ddegrees in the Strontium Barium Nioobate (SBN-60) crystal. Up to 35
