A new approach to design waveguides for supercontinuum generation through dispersive wave emission from optical wave-breaking is proposed in this work. In two steps, the spectral broadening is analytically related to the dispersion curve, and the cross-section of a waveguide is optimized in a few iterations to fit such dispersion profile and, consequently, the target output bandwidth. This strategy does not only improve the efficiency of design tasks, but also provides new insights into the underlying nonlinear processes.
