Paper Abstract

The use of spatial solitons to effect optical interconnects is being actively studied by a number of researchers. Perhaps unjustifiably overlooked in this work is the formation of a grating 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 degrees in the Strontium Barium Niobate (SBN-60) crystal. Up to 35% of the intensity of one beam is transferred into the other; if one beam is interrupted, a significant rise or drop in intensity is observed in the other. Using the two solitons, the control over their own paths, and the exchange of information between them at their intersection, an interconnect system is established. Experimental and theoretical results pertinent to those concepts are presented, and a possible interconnection system based on these ideas is discussed.
