Abstract A new approach is proposed to enhance supercontinuum (SC) spectrum generation in A dispersion-decreasing optical fibre with a new dispersion profile. The chromatic dispersion D(λ,z) is a concave function of wavelengths and has no zero-dispersion wavelengths over the whole or part of the fibre as D(λ,z) is positive. A flatter and much broader spectrum can be produced based on the scheme. The general criteria parameters are obtained for characterizing SC shapes in the optical fibres.
