Abstract

Supercontinuum generation (SCG) in highly nonlinear photonic crystal fibers (PCF) has drawn a lot of attention for the last decade. Pumping such PCFs with high-power picosecond laser pulses enables the creation of broadband and intense light [1]. Picosecond SCG is initiated by modulation instability and as such contains some noise. It is thus of significant interest to reduce the noise. Here we therefore focus on the noise properties of such supercontinuum (SC) generated in tapered PCFs, and that the tapering reduces the noise at the spectral edge.
