Photonic Multiple Microwave Frequency Measurement Based on Frequency-to-Time Mapping
TL;DR: In this paper, a photonic multiple microwave frequency measurement system is presented and demonstrated based on a swept frequency silicon microring resonator (MRR), where the drop-port of a high-Q MRR is employed as a periodic narrowband scanning filter driven by a sawtooth voltage signal.
