Theoretical and Experimental Research of Loss in Optical Fibers
Abstract
The loss formula for optical fibers with constant radius of curvature of their axes is derived by expressing the field outside of the fiber in terms of a superposition of cylindrical outgoing
waves. In this paper we show that the bending losses of fiber modes can be calculated with the help of curvature-loss formula for slab wave guides and the validity of the result by showing that it is in agreement with the known dependence attenuation from parameters of the slab waveguide and of the LP01-mode of the round step-index fiber.
