Optical matching of single-mode fibers with different cross sections in a photopolymerizable composition

Abstract

The possibility of optical matching in a photopolymerizable composition of a pair of single-mode fibers with significantly different core diameters is studied. It is shown that a polymer connector that is formed during self-channelling and interaction of optical beams at 0.63 µm in the photopolymerizable medium ensures an efficient connection of single-mode fibers at a wavelength of 1.55 µm. Results of experiments on the optical formation of matching polymer elements between SMF-28 and CS-980 and between SMF-28 and Ge-507sm single-mode fibers are presented.
