摘要：

All optical structures for signal processing in optical links are studied. Both theoretical and experimental aspects are considered. Two configurations corresponding to frequency selection and frequency rejection are analyzed. First, hybrid circuits based on single mode optical fibers are studied. Frequency rejection circuits are mainly based on unbalanced Mach-Zehnder interferometers, while frequency selection function uses ring resonators, These structures show good stability and are well suited for low frequency signals up to 100Mhz. To meet microwave and millimeter wave ranges, integrated structure are introduced, The design and the realization of a 1.5GHz frequency rejecting falter made on a glass substrate is presented. The realized integrated filter shows a rejection depth better than 30dBe in a 20GHz band.
