Supercontinuum (SC) sources are nowadays widely used as fundamental building blocks in systems enabling a multitude of technologies such as optical frequency metrology, optical coherence tomography and broadband spectroscopy to name a few [1]. Highly nonlinear fibers (HNLF) make up an excellent platform for SC generation as they not only offer high nonlinearity, but also dispersion-engineering and broadband single-mode operation. Broad SC are easily obtained by injecting ultrashort pulses into the anomalous dispersion regime of the HNLF, where the initial propagation is characterized by temporal compression and spectral broadening through solitonic effects. However, after compression each launched pulse tend to fission into several pulses, a process that is very sensitive to noise and can therefore lead to increased shot-to-shot fluctuations [2].
