The Synthetical Effect of both High-order Dispersion and High-order Nonlinearity on Cross-Phase Modulation Instability in Decreasing Dispersion Fiber

摘要

The synthetical effect of both high-order dispersion and high-order nonlinearity on cross-phase modulation (XPM) instability in decreasing dispersion fibers (DDF) is investigated based on extended nonlinear Schrodinger equations. The effects of fourth-order dispersion, quintic nonlinearity and axially-varying dispersion parameter to the gain spectra are analyzed.
