利用两个光波的拍音符产生光微波或毫米波是一种有吸引力的技术，因为它具有频率可调的微/毫米波产生、工作频率的高选择性以及由于基于光子学的方案而产生的信号的高速相位切换等优点。在本文中，我们提出并演示了利用保偏光纤中存在的正交偏振模式同时产生具有精确控制相位差的两个微波信号。实验证实了所产生的两个微波信号之间的相位差具有很高的稳定性和可控性。
Optical microwave or millimeter-wave generation using the beat note of two lightwaves is an attractive technique because of its advantages of frequency-tunable micro/millimeter-wave generation, high selectivity of the operation frequency, and high-speed phase switching of the generated signals owing to the photonics-based scheme. In this paper, we propose and demonstrate the simultaneous generation of two microwave signals with a precisely-controlled phase difference using the orthogonal polarization modes existing in a polarization maintaining fiber. High stability and controllability of the phase difference between the generated two microwave signals was experimentally confirmed.
