ABSTRACT
The precise manner in which radiation disperses away from a soliton in an optical fiber is a topic attracting current attention. The purpose of this paper is to emphasize that there exists a well-developed formalism derived from inverse scattering theory, which has ready application to this problem for the case when the radiation in question forms part of the input pulse to the fiber.
ABSTRACT
In a recent experiment it was demonstrated that polarization-division multiplexing was incompatible with wavelength-division multiplexing. We discuss a theoretical model that explains this result.
ABSTRACT
The problem of optical soliton propagation in the presence of a stochastic perturbation is considered. Two distinct types of stochasticity are distinguished, termed inhomogeneous and homogeneous. For the latter, the appropriate evolution equations for the soliton parameters (the amplitude eta and velocity K) are derived. These are shown to be of the multiplicative Langevin type and are then briefly discussed. Comparison is made with similar studies elsewhere.
ABSTRACT
A first-order spectral perturbation theory of resonant modes that evolve with periodically amplified optical fiber solitons is presented. In contrast with the modulational instability, these modes exhibit a linear growth in amplitude with respect to propagation and have a tuning characteristic that follows an inverse square-root dependence on the amplification period. Numerical results based on a complete solution of the nonlinear Schrödinger equation are also presented that confirm and quantify this behavior.
