Ultrafast Signal Processing Devices

Abstract

One of the important applications of nonlinear optics is ultrafast optical signal processing, such as generation and shaping of ultrashort optical pulses, detection and measurement of ultrafast optical signals, and control of them in the time domain. All-optical signal processing based on NLO interactions offers a variety of possibilities of information processing at high speed unfeasible with electronic or optoelectronic methods. There is an increasing demand for such all-optical techniques for the development of high capacity optical networks. Implementation of waveguide NLO devices for practical use in such an optical network system has been the subject of extensive research work.
