We describe an optical fiber splicing process based on the phenomenon of optical beam self-trapping in photocurable organic materials with light induced increase of the refractive index. The ends of two optical fiber cables to be spliced are immersed in a photocurable material with a gap maintained between them. The terminal ends of individual fibers in each cable are facing their counterparts. Two optical beams are sent from opposite fiber cores to meet each other. The beams increase the refractive index of the material. This results into formation of an optically induced bridge that traps and directs the like beams toward the opposite fiber core. This permanent optical connection can be simultaneously built for all the fibers within each of two cables. The splice connection is tolerant to some inevitable tilt or displacement. The advantages of such an approach are high productivity, maintainability, reliability, and cost efficiency. We report the results of theoretical simulations and experiments that demonstrate the feasibility of the approach.
