Abstract
In this paper, we propose a novel photonic true-time delay beamforming
system for phased array antennas. The system relies on tunable delay lines
which are based on Mach–Zehnder delay interferometers (MZDIs) with
tunable coupling ratio. As the MZDIs are implemented on the polarization
domain, a single optical source and a single piece of polarization
maintaining fiber are required. The proposed implementation is theoretically
assessed and beam squinting is investigated by simulation. A
proof-of-concept experiment that validates the operation principle of the
proposed delay lines is presented.
