1. Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers
Sammanfattning : 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. LÄS MER

4. Three-wave mixing in Josephson travelling-wave parametric amplifiers
Sammanfattning : 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. LÄS MER
5. Fiber optic parametric amplifiers in single and multi wavelength applications
Sammanfattning : 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. LÄS MER
