Study of Self Phase Modulation in Chalcogenide Glass Photonic Crystal Fiber

Abstract:

In this paper, Self Phase Modulation (SPM) in chalcogenide As₂Se₃ glass Photonic Crystal Fiber (PCF) is numerically studied by combining the fully vectorial effective index method (FVEIM) and Split Step Fourier Method (SSFM). The FVEIM is used to calculate the variation of effective refractive index of guided mode (neff), effective area (A_eff), dispersion and non-linear coefficient (γ) with wavelength for different designs of chalcogenide As₂Se₃ PCF. The FVEIM solves the vector wave equations and SSFM solves non linear Schrödinger Equation (NLSE) for the different designing parameter of As₂Se₃ PCF. In case of Self Phase Modulation (SPM), spectral width of the obtained output pulse at d/Λ=0.7 is 1.5 times greater than width of the output pulse obtained at d/L=0.3 using SSFM. Thus we can get the desired spectral broadening just by tailoring the design parameters of the PCF.
