N2 - An all-optical photonic microwave phase shifter that requires only a single dc voltage control to realize continuous 0° to 360° radio-frequency (RF) signal phase shift over a wide frequency range is presented. It is based on using an integrated dual-parallel Mach Zehnder modulator (DPMZM) with a 90° polarization rotator in one arm to generate an orthogonally polarized optical carrier and RF modulation sidebands and using a polarization-dependent optical phase shifter to introduce different optical phase shifts to these orthogonal polarization components. The phase shifter has a fast response time, a high resolution, and a compact structure. Experimental results are presented, which demonstrate a continuous 360° phase shift with a flat phase and amplitude response performance over a microwave frequency range of 6.5-26.5 GHz. © 2016 IEEE.
