Analytical Formulas for Micro-Bending and Surface Scattering Loss Estimation in Tube Lattice Fibers

Simple analytical formulas for micro-bending and surface scattering loss in Hollow-Core Tube Lattice Fibers are here proposed and numerically validated. They can also be applied to other Hollow-Core fibers with similar core-cladding interfaces such as Hybrid cladding Kagome-Tubular, Nested Tubes, and Kagome fibers. Scaling laws for both loss mechanisms are also given and discussed.
