It is predicted numerically that soliton generation by four-wave mixing when the central wavelength of the initial pulse is below the zero-dispersion point of a nonlinear waveguide can be significantly boosted by shock-wave formation that reduces the launching power and extends the efficiency of that process deep inside the normal-dispersion region. Experimental evidence of the validity of this prediction is provided by spectral phase and intensity measurement of the propagated bound-state pulse.
