  2. 1. Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers

    Author : Per Olof E Hedekvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion compensation; nonlinear fiber optics; high-speed communication; four-wave mixing; parametric amplification; noise figure; wavelength conversion; optical phase conjugation; all-optical demultiplexer; mid-span spectral inversion;

    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

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-wave mixing; lumped-element; four-wave mixing; SNAIL; Josephson junction; travelling-wave parametric amplifier; parametric amplifier; parametric amplification; resonant phase matching.; rf-SQUID;

    Abstract : This work explores possibilities of building a wide-band, quantum-limited low-noise amplifier by means of three-wave mixing (3WM) in different kinds of Josephson travelling-wave parametric amplifiers (TWPAs). We extend the theory of the continuous three-mode model to include any number of up-converted modes in the small frequency limit where the frequency dispersion is close to linear. READ MORE

  7. 5. Fiber optic parametric amplifiers in single and multi wavelength applications

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber optical parametric amplifiers; optical time division multiplexing; highly nonlinear fiber; pulse generation; wavelength division multiplexing; optical time domain reflectometry.; four-wave mixing; cross-gain saturation; optical gain and bandwidth; transmission;

    Abstract : This thesis describes fiber optical parametricamplifiers (FOPAs) used in single- and multi-wavelength channel applications.The FOPA was operated as a pulse source in optical transmission systems at bit rates of 10-160 Gb/s. It was evaluated in terms of bit error rate after transmission with link lengths up to 650 km. READ MORE
