Abstract:A manufacturing chain that revolutionizes the production of fibers with highly precise refractive index matching is presented. By integrating iterative refractive index adjustments using reference fibers, a remarkable improvement in homogeneity, reaching 1E-5, was achieved. Conventional methods, such as the MCVD process, are limited to ~1E-4. This enhanced precision was demonstrated through meticulous measurements of core materials and validated in the final fiber. Importantly, the presented manufacturing meth… Show more
