When an ultrafast optical pulse with high intensity is propagating through transparent material a supercontinuum can be coherently generated by self-phase
modulation, which is essential to many photonic applications. However, the
presence of dispersion causes stagnation of spectral broadening past a certain
propagation length, requiring an increased input peak power for further broadening. Overcoming such spectral stagnation will be key to achieve practical integrated supercontinuum devices. We present a concept to drive supercontinuum generation with significantly lower input power. We
demonstrate the effect experimentally in dispersion alternating fiber and numerically in integrated photonic waveguides.
