    Abstract : The Kerr nonlinearity in optical fibres tends to generate signal distortion in dispersion-managed fibre-optic communication systems. Within a wavelength channel, the resulting intrachannel effects are timing jitter, i.e. READ MORE

  3. 3. Noise and Saturation Properties of Fiber Optical

    University dissertation from Chalmers University of Technology

    Author : Per Kylemark; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik; Engineering physics; parametric amplification; dual-pumped; single-pumped; saturation; regeneration; four-wave mixing; nonlinear fiber optics; noise figure;

    Abstract : Fiber Optical Parametric Amplifiers (FOPAs) are based on a highly efficient Four-wave Mixing process in highly nonlinear fibers and have gained a lot of interest since it was shown that a high gain can be obtained. They are multi-functional devices that are not only limited to amplifying signals, but their wide range of applicability also include wavelength conversion, pulse-generation, optical sampling and also regeneration at very high bit-rates.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; nonlinear fiber optics; four-wave mixing; optical phase conjugation; dispersion compensation; mid-span spectral inversion; high-speed communication; all-optical demultiplexer; parametric amplification; wavelength conversion; noise figure;

    Abstract : This thesis deals with two applications of four-wave mixing in optical dispersion-shifted fibers; optical phase conjugation and all-optical switching. The work is a part of an effort to study the upgradability of the existing fiber plant, which is of large economic interest. READ MORE

  5. 5. Linear Models of Nonlinear Systems

    University dissertation from Institutionen för systemteknik

    Author : Martin Enqvist; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear models; nonlinear systems; system identification; stochastic processes; linearization; mean-square error; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : Linear time-invariant approximations of nonlinear systems are used in many applications and can be obtained in several ways. For example, using system identification and the prediction-error method, it is always possible to estimate a linear model without considering the fact that the input and output measurements in many cases come from a nonlinear system.
