Abstract

We propose a simple highly nonlinear photonic crystal fiber for generating supercontinuum (SC) spectrum in telecommunication window. Based on the finite difference method, different properties of highly nonlinear photonic crystal fibers are calculated. It is demonstrated that the nonlinear coefficients more than 113 [Wkm]−1 at 1.0 μm, 71 [Wkm]−1 at 1.30 μm and 51 [Wkm]−1 at 1.55 μm with flattened chromatic dispersion and low confinement losses simultaneously.  Moreover, it is shown that it is possible to generate wide SC spectrum using 1.0 ps input pulses to achieve longitudinal resolution of 1.5 μm and 1.1 μm at 1.06 μm and 1.31 μm center wavelengths, respectively.
