Abstract

By employing the Langevin equation, we have examined a mode coupling in graded index plastic optical fiber. The numerical integration of the Langevin equation is based on the computer-simulated Langevin force. The solution matches the experimental data reported previously. We have shown that by solving the Langevin equation (stochastic differential equation) one can treat a mode coupling in graded index plastic optical fibers, which is result of fiber's intrinsic random perturbations.
