Optical switching and its application in Sonet-based transmission systemsTohme, Philip Edward 24 October 2009 (has links)
This thesis is mainly a survey of optical devices used in optical logic and optical space, time and frequency division switching. These are mainly optical logic devices, optical switches, optical switching matrices, optical memories and optical wavelength multiplexers and demultiplexers and optical wavelength shifters. The devices are based on a variety of operating principles and are implemented with a variety of technologies. The basic principles and technologies are described together with typical performance parameters. The different devices and technologies are compared, and areas of possible improvements indicated. As an application of this survey, the possibility of implementing optical logic circuits and an optical time-division switch for Sonet based transmission systems is discussed. / Master of Science
