Reconfigurable RF Frequency Sniffer Using Tunable Micro Ring Resonator

Abstract

A power-efficient, silicon photonic-based sniffer chip with tunable cascaded ring resonators is used for real-time spectrum sensing of millimeter-wave carrier signals, enabling reconfigurable temporal discrimination using peak group delay and frequency-to-time mapping.
