Abstract

This paper describes the design and performance of a 1:16 GaAs/A1GaAs photonics integrated circuit (PIC) for implementing the beamforming function in an optically controlled phased-array system. The PIC includes independent phase and amplitude control for all 16 channels and is flip-flop bonded onto a GaAs carrier which contains all the electrical track routing, thus leaving greater space on the PIC for electro-optic interaction and also avoiding crossovers between the optical waveguides and electrical tracks.
