The authors present a new method for realising a continuously tunable reflectively tapped optical transversal filter processor. This is based on the use of long chirped fibre Bragg gratings as tapping elements. A continuously tunable optical notch transversal filter is demonstrated with a decade tuning range, the highest reported to date.
