Abstract
Fiber supercontinuum (SC) generation is a well-known process widely studied over the last decade [1]. Recently, the particular case of noise-driven SC has received increasing attention because of novel instability properties and links with other systems in the formation of extreme events [2]. SC fluctuations have been investigated experimentally typically through RF measurements technique [3] or considering only a specific region of the SC spectrum with filtering [2]. Recently, the development of the dispersive time-stretch Fourier transform technique has been applied to map spectral fluctuations of modulation instability sidebands into temporal fluctuations that could be measured using a real time oscilloscope [4]. In this study, we apply the technique of dispersive time-stretching to implement the first complete study of real-time fluctuations across the full bandwidth of a supercontinuum generated around 1550 nm.
