| 摘 要： | In this paper, a new method is proposed to generate broad supercontinuum
(SC) spectra in the single-mode optical fibre with concave dispersion
profile. We numerically simulate pulse evolutions and discuss physics
mechanism in detail for SC spectrum generation in the optical fibre with
concave dispersion profile. Furthermore, general criteria are presented for
specifying the shape of SC spectrum by introducing normalized parameters,
which are related to the fibres and the initial pump pulses. The results
show that the flat and broad SC spectra are indeed generated in our proposed
optical fibre.
