Fiber And Integrated Optical Devices For Signal Processing

The design and performance of some signal processing devcies using fiber and integrated optics are discussed. Analog-to-digital (A/D) conversion, logic, and computation are among the signal processing functions which can be performed using integrated optical devices. Optical fibers can be used for signal delay and storage and for implementing traversal filters and delay-matched filters. Some other interesting possibilities make use of both fiber delay line and integrated optical elements. These include variable-length delay lines and programmabe transversal filters.
