A photonic beamforming network based on phase shifters for microwave wide-band applications
2019 21st International Conference on Transparent Optical Networks …, 2019•ieeexplore.ieee.org
In this paper, the performance of a photonic beamforming network based on phase shift for
microwave applications is analysed. The proposed beamforming network elements are
realised as Si-photonic integrated circuits, exhibiting large phase shift (> 360°) and limited
amplitude fluctuations (~ 3 dB). Extremely low signal distortion is demonstrated, by
emulating the transmission of a 1-GHz chirped signal by a 4-element phased array antenna
operating beam steering, driven by the proposed beamforming network.
