Abstract

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° phase-shift tuning range with a single external electrical control. A prototype of the rf photonic phase shifter with a frequency of 26.75GHz and 360° tuning range is experimentally demonstrated.
