Study of the Mach-Zehnder interferometric technique for dielectric resonator tuning

摘要

The modulation of a metallic microwave-scale Mach-Zehnder interferometer (MZI) coupled to a dielectric resonator (DR) may be used to tune the resonance frequency of the latter. In this paper, we report on a theoretical study to develop an understanding of the intrinsic tuning properties of an MZI Ring-DR-Microstrip line system and, for the first time, present an experimental verification of the concept.
