Generation of Flat Supercontinuum in a Single-mode Optical Fiber with a Convex Chromatic Dispersion Profile
摘要
Abstract
A single-mode optical fiber with a convex chromatic dispersion profile is proposed for generating a flat supercontinuum(SC). The fiber has normal dispersion and the dispersion parameterD(λ,z)is a convex function of wavelengths. It is shown from the numerical results that the chromatic dispersion, the flatness of the dispersion curve and the pump conditions have significant effect on SC generation. A flat and broad SC without strong residual pump component can be obtained when the pump wavelength is set in the vicinity of the wavelength at which the fiber has small normal group-velocity dispersion(GVD) and small dispersion slope. The fiber with a smaller normal GVD, a flatter dispersion profile and a higher nonlinear coefficient are more suitable for broad SC generation.
