提出了一种利用射频频率对微波和毫米波信号进行真实的实时分离的方法。该方法是采用一个集成的光学布拉格光栅法布里-珀罗（BGFP）设备的空间分离的光调制微波信号的高分辨率。通过使用集成光学混合衍射透镜扩束器来向BGFP提供所需的光学波前，实现了紧凑性。在1至23 GHz范围内进行了原理验证测量，峰值精细度为27。理论分析，制作过程，实验结果，局限性，和改进。
A compact means to separate microwave and millimeter-wave optical signals by RF frequency in real time is demonstrated. The approach is to employ an integrated optical Bragg grating Fabry-Perot (BGFP) device to spatially separate optically modulated microwave signals with high resolution. The compactness is achieved through the use of an integrated optical hybrid diffractive lens beam expander to provide the required optical wavefront to the BGFP. A proof-of-principle measurement was performed from 1 to 23 GHz with peak finesse of 27. The theoretical analysis, fabrication procedure, experimental results, limitations, and improvements are described.
