Dynamics of Solitary Wave Pulses Near the Zero-Dispersion Wavelength in Optical Fibers

摘要

A theoretical study was made of the propagation characteristics of solitary wave pulses near the zero-dispersion wavelength (ZDW) in optical fibers. A variety of solitary wave profiles are possible near the ZDW and some of them are found to be stable to perturbations. These findings might prove of some technological significance in long-distance communications, as second-order dispersion vanishes at the ZDW so the newly discovered solitary waves, which are of shorter duration than the usual solitary waves in the anomalous dispersion regime, could be utilized to increase the transmission bit rate.
