利用差分群延迟元件和光相位调制器的偏振敏感效应，设计了一种稳定的线性光子射频移相器。对于40 GHz以上的RF信号，相移可以在360度上连续调谐，电控制电压为-7.5至+7.5V。
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 degrees for RF signals over 40GHz with an electrical control voltage from -7.5 to +7.5V.
