Mathematical Technique for Photonic Crystal Fibers Automated Positioning Module

In this paper, the dependence of the optical signal loss on the displacement of photonic crystal fibers during the connection is considered. The method based on the principles of matched filtration and autoconvolution was used for the positioning of photonic crystal fibers and quality control of their connection. This method has high noise immunity. Experimental studies have shown that even with the presence of significant distortions of the optical field image of the photonic crystal fiber, this method allows to determine with sufficient accuracy the position of the photonic crystal fiber axis.
