Improved dual-wavelength-pumped supercontinuum generation in an all-fiber device

Abstract

we propose the improved dual-wavelengthpumped scheme based on the former work (C.Xiong et al, Journal of lightwave tech. 27, 1638-1643(2009)), which can obviously increase the power at the visible wavelengths and effectively improve the flatness of spectra by solving the Generalized Nonlinear Schrödinger Equation with the adaptive split-step Fourier method and simulating supercontinuum generation.
