提出并论证了一种基于正交和相参光载波的光辅助微波混频技术。在光域实现了高质量的二相移键控、移幅键控和开关键控微波调制。对所提出的混合装置的超高带宽响应进行了分析和比较。采用所提出的信号混频技术，提高了光纤无线通信系统中光子微波信号的相位稳定性。
An optical-assisted microwave-mixing technique based on orthogonal and phase-coherent optical carriers is proposed and demonstrated. High-quality binary-phase-shift keying, amplitude-shift keying, and on-off keying microwave modulation at 20 GHz implemented in the optical domain have been tested. The ultra-high-bandwidth response of the proposed mixing device is also analyzed and compared. The phase stability of the photonic microwave signal in the radio-over-fiber system is improved by the proposed signal mixing technique.
