Distributed loss and mode coupling and their effect on time-dependent propagation in multimode fibers
Abstract:
A first-order solution to the transport equation for the total power propagating in each degenerate mode group of a multimode fiber is used to describe pulse propagation in multimode fibers. The basic transport equation is supplemented by models for Rayleigh-scattering-induced losses, mode coupling, and the modal group velocity function. Each of these models can be specified for a particular fiber from a standard set of near-field measurements and then incorporated into pulse propagation simulations, which closely matched the measured pulse response of test fibers.

Propagation of Waves
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Attenuation
When constant series resistance and shunt conductance are present, voltage and current equations are modified. The propagation constant indicates that voltage and current waves consist of both forward and backward traveling components. These waves attenuate as they propagate, with the attenuation factor related to the resistance and conductance. In a...
