Paper Abstract

This paper discusses the synthesis and design procedures for implementation of microwave filters with adjustable transfer functions using fiber optic delay lines along with electro-optical couplers (EOC). It presents two configurations for realizing narrow-band and wide-band filters. It numerically investigates several design configurations in which the desired transfer functions are obtained by adjusting the coupling ratios in EOCs. The paper also discusses the effect of random variations in the length of delay lines and the coupling ratios of EOCs on the transfer function of the filters.
