    "abstract": "The dynamics of a soliton propagating in a single-mode optical fiber with\ngain, loss, and Raman coupling to thermal phonons is analyzed. Using both\nsoliton perturbation theory and exact numerical techniques, we predict that\nintrinsic thermal quantum noise from the phonon reservoirs is a larger source\nof jitter and other perturbations than the gain-related Gordon-Haus noise, for\nshort pulses, assuming typical fiber parameters. The size of the Raman timing\njitter is evaluated for both bright and dark (topological) solitons, and is\nlarger for bright solitons. Because Raman thermal quantum noise is a nonlinear,\nmultiplicative noise source, these effects are stronger for the more intense\npulses needed to propagate as solitons in the short-pulse regime. Thus Raman\nnoise may place additional limitations on fiber-optical communications and\nnetworking using ultrafast (subpicosecond) pulses.",
