摘要
受激布里渊散射效应被广泛用于微波光子学频率测量中, 然而该效应的测频系统存在扫描时间长、响应速度慢的问题, 为了提高该系统的扫描效率, 提出了基于频率梳泵浦和游标效应的改进方案。阐述了此方案的测频原理和改进机制, 并进行了理论分析和仿真验证。改进后的系统在频率测量精度100 MHz、系统带宽50 GHz时, 扫描次数降低为原来的7%, 在相同精度和扫描次数下, 带宽更大, 表明新方案的系统性能得到了大幅提升。
Abstract
Stimulated Brillouin scattering is widely used in microwave photonics frequency measurement, however systems based on stimulated Brillouin scattering have long scanning period and low response speed. To improve the scan efficiency, an improved scheme using frequency combs pump and vernier effect was studied. The improved system was analyzed and simulated, and the scanning number was reduced to 7% of the original result under 100 MHz precision and 50 GHz bandwidth. Moreover, when the precision and scanning number are fixed, the improved system has a greater bandwidth which indicates that the property of the system is greatly enhanced.
