Abstract
We experimentally and numerically demonstrate a simple and general technique to reduce the noise of modulational instability and soliton-based broadband supercontinuum lasers at the pulse-to-pulse level. Because of the requirement of low cost and high average power, such supercontinuum lasers constitute 99% of today’s commercially available supercontinuum lasers. The technique relies on adding a short normal dispersion fiber to force the spectrally and temporally distributed solitons to spectrally broaden through self-phase modulation (SPM) and thereby overlap to average out the noise. We experimentally demonstrate that this SPM technique provides significant noise reduction over a broad bandwidth.
