ANALYTICAL DESCRIPTION OF CROSS-PHASE MODULATION IN DISPERSIVE OPTICAL FIBERS

The effect of intensity distortion induced by cross-phase modulation i n dispersive optical fibers is studied. It is shown that, in most conf igurations in which distortions that are due to cross-phase modulation can become significant to optical communications, the effect of cross -phase modulation can be described with excellent accuracy by simple a nalytical expressions. The presented analysis also suggests that inten sity distortions owing to cross-phase modulation can be efficiently re duced by Linear dispersion compensation. (C) 1998 Optical Society of A merica.
