An RF Scanning Receiver on a Silicon Photonic Chip

We experimentally demonstrate the first on-chip broadly-tunable RF scanning receiver, using silicon photonic technology. By exploiting an innovative and simple noise-cancelling architecture, the device, fabricated using a multi-project-wafer service, achieves ultralow-noise operation in the frequency range of 0-35GHz, with an unprecedented image rejection ratio >80 dB, in an antenna-remoting scenario.
