【 摘 要 】

This study reports and experimentally demonstrates a programmable on-chip photonic processor towards different RF receiver configurations. The Si₃N₄ processor is built by interconnecting independent subunits such as simple and complex Mach-Zehnder interferometers and Ring resonators. The design, fabrication, and characterization of a dedicated chip are described. As a proof of concept, it can be used as a reconfigurable filter with distinct frequency response. More importantly, a thorough RF receiver related passive processor including out-of-band suppression, carrier-sideband routing, channelization filtering, as well as I-Q mixing prior to an optical detection stage. This is effective proof of a programmable integrated processor encompassing most passive filtering and routing subunits for broadband photonic RF receiver.
