Paper Abstract

A macrobending loss formula for single-mode fibers, which is shown to accurately predict the bend loss of a single-mode fiber with complex or real refractive index coating, is presented. Theoretical simulations and experimental measurements of bend loss in a fiber with nickel coating obtained by chemical plating and acrylate buffer coating are also presented. Agreements between simulations and measurements support the validity of the theoretical formula. Results show that the large imaginary part of the refractive index of the coating can intensify the bend loss oscillation behaviors, which implies that the bent fiber with metal coating can be utilized in fiber-optic devices.
