Abstract
A dispersive and saturable medium is shown, under very general conditions, to possess ultrafast dynamic behaviour due to non-adiabatic polarisation dynamics. Simple analytical expressions relating the effect to the refractive index dispersion of a semiconductor ire derived and the magnitude of the equivalent Kerr coefficient is shown to be in qualitative agreement with measurements on active semiconductor waveguides.
