Description
technical field [0001] The invention belongs to the technical field of optical fiber cutting, and in particular relates to a method and a system for optimizing cutting conditions based on the simulation of the fracture surface type of optical fiber cutting. Background technique [0002] The quality of fiber end faces is the key to realizing high-quality termination and fusion splicing between fibers, fiber-optical waveguide coupling, and fiber-semiconductor laser die coupling. At present, cutting and grinding are generally used to obtain high-quality fiber end faces. With the development of optical fiber technology, the structure of optical fiber is becoming more and more complex. Photonic crystal optical fibers and some special material optical fibers that are made of a single material and realize light guiding and performance regulation through periodic structures have appeared. The grinding technology requires ultra-fine grinding. Materials and solvents are not suitable f...
