Propagation in Irregular Optic Fibres

Abstract

In a recent work (see [B]) we described how to calculate the attenuation in an optical fiber which presents random microdefects.We considered defects which can be described by functions depending only on the longitudinal coordinate, z. For instance, it can be a fiber whose core radius is given by one random process: ρ_ω(z) or it can be a fiber which has constant core radius but presents microbends, in this case one considers that its axis coordinates are given by two random processes: $x_\omega ^0 (z)$ and $y_\omega ^0 (z)$.
