Abstract : The objective of this program was to develop new techniques for the processing of wideband analog signals based upon the use of optical fiber delay lines. During the course of the research, new concepts in optical processing have been developed and demonstrated. A new type of reflective tap was studied in which an internal mirror is fabricated in a continuous length of fiber. Operation of a reflectively tapped transversal filter with a bandwidth of 10 GHz was demonstrated, the highest bandwidth reported to date for any signal processor. This device has performed 1011 analog multiplications per second in a relatively simple processor design. It is also possible to perform optical simulation of radar targets using the reflectively tapped fiber. Fiber delay lines, transversal filters, broadband signal processing.
