High-order solitons transmission in hollow-core photonic crystal fibers

Hollow-core photonic crystal fibers (HC-PCFs) can be used for the supercontinuum generation. Because the design of HC-PCFs is flexible, the dispersion and nonlinear effects is variable, and the pulses in HC-PCFs can show different transmission characteristics. In this paper, the transmission of high-order solitons in HC-PCFs is studied. Through adjusting the group-velocity dispersion and nonlinear effects of HC-PCFs, we present the different transmission of high-order soli(t)ons, and analyze their characteristics. Results are conducive to the applications of HC-PCFs in nonlinear optics and ultrafast optics. Copyright (C) EPLA, 2016
