Summary:Silicon photonics chips have enormous development potential in the integration and miniaturization of microwave photonic systems. A photonics-assisted joint communication and radar (JCR) system in the millimeter-wave (mmW) band based on a novel silicon photonics front-end module (FEM) is proposed and demonstrated. The FEM mainly integrates an intensity modulator, a photodetector, a variable optical attenuator, and a 2×2 optical coupler. In the proof-of-concept experiment, JCR signals in a time-division multiplexing pattern with different bandwidths centered on the 28 GHz were generated. A 36-Gbit/s communication rate over a 2-m wireless distance was successfully achieved. Furthermore, a range detection accuracy of less than 12.3 mm for single user and a range resolution of 49.4 mm for two users were observed.
