Abstract

Integrated waveguide meshes have been recently proposed as an advanced technical solution for the implementation of universal processors. In this paper we investigate their potential for the implementation of simple and cascaded programmable RF-photonic filters. We specifically address the case of single sideband and carrier injection filters and the possibility of implementing parallel filtering schemes. We demonstrate an extensive amount of device flexibility including: circuit design topology, filter tunability and reconfigurability. The device composed of 7-cells allows the synthesis of basic photonic circuits and more complex cascaded combinations of ring resonators and Mach-Zehnder interferometers.
