90-Degree Optical Hybrid（90度光学混频器）是一种用于相干光通信系统中的关键器件，能够将输入的光信号与本地振荡器光信号进行混频，输出四个相位差为90度的光信号分量（I+、I-、Q+、Q-），用于后续的光电探测和数字信号处理，实现对光信号幅度和相位的完整检测。

Product Description - Optical Hybrid Six-port hybrid devices have been used for microwave and millimeter-wave detection systems since the mid-1990s and are a key component for coherent receivers. In principle, the six-port device consists of linear dividers and combiners interconnected in such a way that four different vectorial additions of a reference signal (LO) and the signal to be detected are obtained. The levels of the four output signals are detected by balanced receivers. By applying suitable baseband signal processing algorithms, the amplitude and phase of the unknown signal can be determined. For optical coherent detection, the six-port 90° optical hybrid would mix the incoming signal with the four quadratural states associated with the reference signal in the complex-field space. The optical hybrid would then deliver the four light signals to two pairs of balanced detectors. See below block diagram for 90° optical hybrid and a coherent receiver.
