By cascading soliton compression in an anomalous dispersion fiber and optical wave-breaking in a normal dispersion fiber, we demonstrate a coherent ultra-low noise fiber SC source covering the 930 - 2130 nm range.

Many ultrafast optics applications require uniform and smooth spectral and temporal intensity profiles of ultrashort laser pulses. All normal dispersion (ANDi), coherent light pulses from fiber-based supercontinuum (SC) are often assumed to fulfill t
