A coupled variable-coefficient higher-order nonlinear Schrödinger equation in birefringent fiber is discussed, and an analytical Peregrine soliton solution with two peaks is derived by means of the Darboux transformation method. The controllable behaviors of this Peregrine soliton with two peaks are investigated in a periodic dispersion system and a dispersion decreasing fiber with exponential profile. In these systems, the effective propagation distance Z appears a maximum Z m . Comparing this maximum with values of peak location Z p , the initial excitation, peak excitation, rear excitation and periodic excitation are constructed.

“…The third and fourth terms in Eq. (7) correspond to the dispersion, the fifth term corresponds to self and cross phase modulation, the sixth term describes the shock effect and the last term corresponds to the linear coupling [12,13,25]. These equations were solved numerically using a split step Fourier (SSF) method for 200 fs pulses.…”

“…Waves are guided in this PCF by total internal reflection (TIR) due to the refractive index difference between soft glass and LC. Modal characteristics of regular dual core PCFs with air filled cladding holes were investigated by using the vector finite element method (FEM) [11][12][13]. In this study, we used the similar numerical tools to evaluate wavelength dependent dispersion and coupling characteristics of LC-PCF couplers.…”

Abstract-We propose an all optical switch in a dual-core photonic crystal fiber (PCF) that has the core region consisting of soft glass and has nematic liquid crystal filled holes in the cladding region. Light waves are guided in this PCF by total internal reflection (TIR) due to the refractive index contrast between soft glass and liquid crystal (LC). Its wavelength dependent coupling, birefringence and dispersion are calculated and later use these parameters to evaluate the switching characteristics of short pulses propagating through this optical waveguide. The switch demonstrates tunability with external perturbation such as applying external heat source or electric field. Refractive index sensitivity of LC with these perturbation as well as polarization of the light signal determines the coupling, birefringence and dispersion properties of the overall waveguide and its switching characteristics.
