Abstract

Broadband multibeam phased array antennas play a crucial role in wireless communication, satellite communication, and radar systems. Microwave photonics and photonic integration circuit technologies offer the benefits of ultralow transmission loss, extensive operating bandwidth, electromagnetic immunity, and various multiplexing schemes, thereby providing robust technical support for broadband multibeamforming networks. In this letter, a broadband optical multi-beamforming network architecture combining both transmission and reception using optical true time delay is proposed and demonstrated by simulation. A 3×3 broadband multibeamformer based on the architecture is designed and fabricated on an 8mm × 3mm silicon-on-insulator chip.
