Spectral hole-burning (SHB) technology is considered for >10-GHz instantaneous bandwidth signal-processing applications. In this context we report on what is believed to be the first demonstration of a SHB microwave spectrometer. A set of gratings engraved in a SHB crystal is used to filter one sideband of the optically carried microwave signal. The setup is confined to narrow-bandwidth operation, over a 35-MHz-wide interval. The first findings confirm the validity of the architecture in terms of spectral resolution, angular channel separation, and simultaneous detection of multiple spectral lines.
光谱烧孔（SHB）技术被考虑用于大于10 GHz的瞬时带宽信号处理应用。在此背景下，我们报告了据信是首次演示的SHB微波光谱仪。刻在SHB晶体中的一组光栅用于过滤光载波微波信号的一个边带。该装置限于在35 MHz宽的间隔内进行窄带宽操作。初步研究结果证实了该架构在光谱分辨率、角通道分离和多条谱线同时检测方面的有效性。
