提出了一种产生正交偏振单边带调制信号的新方法。该调制方案是基于光单边带调制信号的光载波的全光受激布里渊散射处理，通过这种非线性效应引起的偏振态拖曳。这种调制技术可以用于几种微波光子学应用，例如天线波束成形或微波光子学滤波器。为了执行概念验证实验，部署正交调制器来实现RF移相器。
We present a novel technique to generate orthogonally polarized optical single sideband modulated signals. The modulation scheme is based on all optical stimulated Brillouin scattering processing of the optical carrier of an optical single sideband modulated signal, by means of the polarization state dragging induced by this non-linear effect. This modulation technique can be used in several microwave photonics applications, such as antenna beamforming or microwave photonics filters. In order to perform a proof-of-concept experiment, the orthogonal modulator is deployed for the implementation of an RF phase-shifter.
