Fundamental noise limitations to supercontinuum generation in microstructure fiber.
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 an...
متن کاملNoise amplification during supercontinuum generation in microstructure fiber.
Supercontinua generated by femtosecond pulses launched in microstructure fiber can exhibit significant low-frequency (<1-MHz) amplitude noise on the output pulse train. We show that this low-frequency noise is an amplified version of the amplitude noise that is already present on the input laser pulse train. Through both experimental measurements and numerical simulations, we quantify the noise...
متن کاملFundamental amplitude noise limitations to supercontinuum spectra generated in a microstructured fiber
Broadband supercontinuum spectra are generated in a microstructured fiber using femtosecond laser pulses. Noise properties of these spectra are studied through experiments and numerical simulations based on a generalized stochastic nonlinear Schrödinger equation. In particular, the relative intensity noise as a function of wavelength across the supercontinuum is measured over a wide range of in...
متن کاملBroadband noise on supercontinuum generated in microstructure fiber
The broad supercontinuum generated by pumping highly nonlinear microstructure fiber with a femtosecond laser exhibits broadband amplitude noise. We experimentally investigate this amplitude noise as a function of wavelength, input pump power, and chirp. OCIS codes: 190.4370, 190.7110
متن کاملAdaptive femtosecond pulse shaping to control supercontinuum generation in a microstructure fiber
Efficient confinement of laser radiation in the core of a photonic crystal fiber increases the nonlinear processes resulting in supercontinuum generation. The technique of adaptive pulse shaping using an evolutionary algorithm provides a method to gain control over such highly nonlinear processes. Adaptive pulse shaping of the driving laser radiation passing through the photonic crystal fiber i...
