E 66, 046627 (2002) | Subject: | Optics; Data Analysis, Statistics and Probability; General Physics | physics.optics cond-mat physics.data-an physics.gen-ph | Abstract: | We model the effects of cross-phase modulation in frequency (or wavelength) division multiplexed optical communications systems, using a Schrödinger equation with a spatially and temporally random potential. Green’s functions for the propagation of light in this system are calculated using Feynman path-integral and diagrammatic techniques. This propagation leads to a non-Gaussian joint distribution of the input and output optical fields. We use these results to determine the amplitude and timing jitter of a signal pulse and to estimate the system capacity in analog communication. | Source: | arXiv, physics/0210062 | Services: | Forum | Review | PDF | Favorites |
