Modeling and simulation of macrobending losses in metal-coated single-mode fibers

Abstract

A formula for calculating macrobending losses in single-mode fibers with metal coating is derived. The macrobending losses in a standard single-mode fiber coated with different metal coatings are simulated using this formula. Simulation results indicate that metal coating will induce strong bend loss oscillations as a function of bend radius and the stronger bend loss oscillations of the metal-coated fiber occur with the decrease of bend radius; the wavelength and coating refractive index also have significant impact on the fiber bend losses.
