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.
我们提出了一种生成正交偏振光单边带调制信号的新技术。该调制方案基于对光单边带调制信号的光载波进行全光受激布里渊散射处理，利用这种非线性效应引起的偏振态拖曳。这种调制技术可用于多种微波光子学应用，如天线波束形成或微波光子学滤波器。为了进行概念验证实验，将正交调制器用于实现射频移相器。
