The paper studies the optical solitons with coupled nonlinear Schrödinger system (CNLSS) that describes the propagation of waves in birefringence polarization-preserving fibers with four-wave mixing effect. The system is discussed with the effects of group velocity dispersion, self-phase and cross-phase modulations. The mechanism that is used to investigate is the extended Fan-sub equation method. It is observed that this system exhibits a collection of rich solitons (single and combined) for different values of parameters. The 3D figures are also plotted to show the physical behavior of obtained solutions under different constraint conditions.

Linear And Nonlinear

Accurate wavelength scanned four-wave mixing (FWM) measurement results in an optical fiber are presented with two tunable laser sources near the dispersion-zero wavelength of the fiber. By comparing the measured FWM data with a simple analytic expression, we have demonstrated that important linear and nonlinear optical properties such as zero-dispersion wavelength, dispersion slope and nonlinear refractive index of the sample fiber. Highly accurate and repeatable measurement results for a sample fiber are presented. Temperature-dependent change in the chromatic dispersion of a fiber is also investigated.
