Coherent Optical Fibre Delay-Line Processor

Abstract

The operation of an optical fibre tapped delay line with a long coherence length source is described. Optical phase is retained; thus the system can perform bipolar (or in general complex-valued) signal processing operations. Experimental results are presented that illustrate the operating characteristics and capabilities of the system for simple time-domain processing operations. © 1986, The Institution of Electrical Engineers.
