Integrated microwave photonic filter for wideband RF receiver
Abstract
Wideband Radio Frequency (RF) receiver are crucial for enabling higher data rates and increased resolution radar systems. However, the RF spectrum is getting more crowded, congested, and contested, and signal pre-processing to prevent distortion from interfering signals and saturation of the receiver are urgently needed; traditional electronic approaches lack bandwidth, frequency selectivity,and tunability, requiring new solutions. Integrated Microwave Photonics (MWP) promises efficient wideband signal processing in a compact chip-scale formfactor by transducing the microwave signal onto an optical carrier and utilizing optical signal processing techniques. In this project, we will demonstrate a photonic chip-based filter that frequency selectively suppresses interfering signals.This filter will establish a new paradigm of analog signal processing for wideband receivers, simultaneously offering wideband operation (tens of GHz), high-frequency resolution (a few tens of MHz), and low latency combined with the compactness and robustness (nomoving parts) of solid-state integration technology.
