Photonic radio-frequency phase shifter based on polarization interference.
An rf photonic phase shifter based on polarization interference is presented, and the theoretical fundamentals of the design are explained. This phase shifter provides broad operational bandwidth and a full 360 degrees phase-shift tuning range with a single external electrical control. A prototype of the rf photonic phase shifter with a frequency of 26.75 GHz and 360 degrees tuning range is experimentally demonstrated.
