متن کاملNonlinear Microstructure Fibers
Due to the long interactive length that light has with the glass media of an optical fiber there tend to be nonlinear optical effects. With the advent of microstructure fibers it is possible to tailor the fiber to reduce or enhance the nonlinear effect of light propagating down a fiber. This paper will give an overview on microstructure fibers and how they are used in nonlinear optics application.
متن کاملBayesian Spectrum and Chirp Analysis
We seek optimal methods of estimating power spectrum and chirp (frequency change) rate for the case that one has incomplete noisy data on values y(t) of a time series. The Schuster periodogram turns out to be a \su cient statistic" for the spectrum, a generalization playing the same role for chirped signals. However, the optimal processing is not a linear ltering operation like the Blackman{Tuk...
متن کاملFundamental 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 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...
