Quantifying the impact of pump noise on fiber-optic nonlinear processes

The impact of pump pulse fluctuations on ultrafast nonlinear frequency conversion processes in optical fibers is investigated. A simple measure of the sensitivity of a particular process to pump technical noise is introduced and tested against numerical ensemble simulations for normal-dispersion continuum generation and dispersive-wave generation. The proposed measure is found to adequately describe the impact of technical noise at the per mill or percent level.
