Abstract A new chromatic dispersion profile of a single-mode optical fibre is proposed for generating a supercontinuum with a flatly broadened spectrum. The chromatic dispersion D(λ,z) is a convex function of wavelengths and has no zero-dispersion wavelengths over the whole part of the fibre as D(λ,z) is negative. It is shown that the flat supercontinuum spectrum is obtained when the pump wavelength is set in the vicinity of the wavelength at which the peak chromatic dispersion is near zero and the strong residual pump component is eliminated.
