The Dispersion Effect in Photonic Crystal Fibers

Abstract

Based on the Harmonitor theory of field in PCFs in which the second order differential to the transmission distance is included, and by the Darboux solution, the dispersion effect on the field is re-discussed. The results can be used in the dispersion parameter design of photonics crystal fibers. The field will expand and split faster than that in common fibers so that (as the description of Harmonitor theory) the higher-order dispersion should be taken into account. The high-order dispersion can also induce pulse compression while its pre-order dispersion values are zeroes. The dispersion coefficient changes with distance.
