In this paper, Self Phase Modulation (SPM) in chalcogenide As2Se3glass 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 (Aeff), dispersion and non-linear coefficient (γ) with wavelength for different designs of chalcogenide As2Se3PCF. The FVEIM solves the vector wave equations and SSFM solves non linear Schrödinger Equation (NLSE) for the different designing parameter of As2Se3PCF. 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.

3R Regeneration

A scheme to achieve 40Gb/s all-optical 3R-regeneration through cross-phase modulation and self-phase modulation is studied in this paper. The core of the scheme is to use ultra-highly nonlinear photonic crystal fiber as the Mach-Zehnder interference of one arm. Length of the photonic crystal fiber at the arm is adjusted after calculation so as to make the signal light through the arm produce nonlinear phase shift of by means of XPM effect, then mutual interference between the resulting light and the optical signal at the other arm is generated and the noise interfusing the system is eliminated to make the signal be regenerated. Furthermore, self-phase modulation effect of the fiber is applied to make further optimization of the signal, with Optisystem for simulation experiment.

All-optical multicasting of performing data routing from single node to multiple destinations in the optical domain is promising for next generation ultrahigh-peed photonic networks. Based on the self-phase modulation in dispersion flattened highly nonlinear photonic crystal fiber and followed spectral filtering, simultaneous 1-to-8 all-optical wavelength multicasting return-to-zero (RZ) signal at 20 Gbit/s with 100 GHz channel spaced is achieved. Wavelength tunable range and dynamic characteristic of proposed wavelength multicasting scheme is further investigated. The results show our designed scheme achieve operation wavelength range of 25 nm, OSNR of 32.01 dB andQfactor of 12.8. Moreover, the scheme has simple structure as well as high tolerance to signal power fluctuation.
