SIMULATIONS OF CONNECTION OF OPTICAL FIBER CIRCUITS BY OPTICAL BEAM SELF-TRAPPING IN PHOTOCURABLE MEDIA

Simulations of optical fiber splicing process based on the phenomenon of optical beam self-trapping in photocurable organic materials (PM) with light induced increase of the refractive index have been done. Cases of single-mode and multi-mode fibers are considered. The terminal ends of individual fibers in each cable are immersed in a PM at some distance and are facing their counterparts. Two ultra-violet beams are sent from opposite fiber cores to meet each other. These writing beams increase the refractive index of the PM. This results in a formation of an optically induced bridge that traps and directs the beams toward the opposite fiber core.
