Abstract

We demonstrate a stable and linear photonic radio frequency (RF) phase shifter based on a differential-group-delay element and the polarization sensitive effect of an optical phase modulator. The phase shift can be tuned continuously over 360° for RF signals over 40GHz with an electrical control voltage from −7.5 to +7.5V.
