Paper Abstract

Optical delay-line networks are investigated for electrical signal filtering applications. Results concerning the microwave frequency response of some basic structures such as unbalanced Mach-Zehnder interferometers and ring resonators based on fiber-optic components are briefly summarized. We report the microwave performance of some integrated unbalanced Mach-Zehnder interferometers fabricated in glass by a silver ion-exchanged process. These devices can be used as microwave notch filter in the 1.5 GHz - 15 GHz range. At the resonance frequencies, a rejection depth of over 30 dBe was obtained. Furthermore, we focus on the interference effects of the light carrier which can occur, even in the incoherent regime, when basic structures are cascaded in order to perform complex filtering responses. These include the role of optical phase shift and polarization dependence. A new transfer matrix analysis is introduced for modeling the microwave response of cascaded devices showing good agreement with experiments.
