Programmable RF photonic phase shifters based on FD-OP for optically controlled beamforming
Multiple photonic phase shifters with low PN (phase noise) are achieved simultaneously. The phase shifter with low amplitude variation of <2.5dB is achieved. The phase shifter with phase deviation of <2 at 15GHz is achieved. The beam forming network can scan arbitrary beam angles because all the phase shifters have continuous phase control.
