  • Abstract
    A new type of transversal filter for RF and microwave signals on an optical carrier is described. It is based on the coupling and delay between different spatial modes of a solitary few-moded optical fibre. The principle is demonstrated experimentally by constructing four point rectangular and Hamming filters from standard telecommunication fibre using microbend couplers.
