| Abstract: | A theoretical investigation with the method of split-step Fourier is presented on the nonlinear propagation and supercontinuum generation of laser pulse in a photonic crystal fiber.The impact of the power of the initial laser pulse and nonlinear effects on spectral shape and band width is calculated and analyzed.The band width of the supercontinuum is found to be related to wavelengths of the initial laser pulse. |

| Keywords: | supercontinuum photonic crystal fibers split-step Fourier method |
