A novel ring resonator-based photonic beamformer has been developed for continuous and squint-free control of the reception angle of broadband phased array antenna systems. The core of the system is a ring resonator-based optical beamforming network (OBFN) used for delay synchronization and coherent signal combining. The OBFN is integrated in a single chip realized in CMOS-compatible optical waveguide...
A squint-free, continuously tunable optical beamformer system for phased array receive antennas is proposed and experimentally demonstrated, which involves an integrated ring resonator-based optical beam forming network, filter-based optical SSB-SC modulation and balanced coherent detection.
A novel beam steering mechanism for a phased array antenna receiver system is introduced. The core of the system is a ring resonator-based integrated optical beam forming network chip. Its principles are explained and demonstrated by presenting some measurement results. The system architecture around the chip is based on a combination of frequency down conversion, filter-based optical single sideband...
