Phys. Rev. Lett. 90, 113904 (2003) [4 pages]Fundamental Noise Limitations to Supercontinuum Generation in Microstructure FiberReceived 26 November 2002; published 21 March 2003 Broadband noise on supercontinuum spectra generated in microstructure fiber is shown to lead to amplitude fluctuations as large as 50% for certain input laser pulse parameters. We study this noise using both experimental measurements and numerical simulations with a generalized stochastic nonlinear Schrödinger equation, finding good quantitative agreement over a range of input-pulse energies and chirp values. This noise is shown to arise from nonlinear amplification of two quantum noise inputs: the input-pulse shot noise and the spontaneous Raman scattering down the fiber. © 2003 The American Physical Society URL:
