Paper Abstract

In this paper we present a 4-channel silicon photonic true-time delay (TTD) beamformer in which the phase of each channel is automatically adjusted in real-time. Beamforming was demonstrated with a 1 Gb/s QPSK signal carried at 28 GHz. The demonstration comprised the following custom made devices: two arrays of GaAs Mach-Zehnder modulators (MZMs), a radiation-hardened 7-core erbium-doped fiber amplifier (MC-EDFA) for power boosting, and a silicon photonic integrated circuit (PIC) containing a 4 × 1 TTD optical beamformer network (OBFN). Having provided a successful proof-of-concept demonstration, the dimensioning of an end-to-end photonic-aided payload receiver is here studied. It comprises the proposed OBFN fed by 100 antenna elements (AEs) in a multibeam scenario, also providing an estimation of the system’s power consumption.
