| 摘 要： | 针对星间激光通信系统,分析了光纤光栅在此系统中的应用。为了设计出高性能的光滤波器以满足星间激光通信系统的要求,研究了光滤波器的带宽对系统性能的影响。在GEO-LEO星间链路中,考虑多普勒频移,研究了系统的归一化信噪比与滤波器带宽的关系,提出并设计了滤波器最佳带宽。根据得到的最佳带宽,设计了符合要求的光纤光栅滤波器。

| Abstract: | The use of fiber grating is analyzed in inter-satellite laser communications system.To satisfy the requirements of beacon sub-system,the effects of optical filter bandwidth on communication performance were researched in the design of high performance optical filter.In GEO-LEO laser communications system, considering Doppler Shift,the relation of the normalized SNR(Signal to Noise Ratio) and filter bandwidth was analyzed and the optimum bandwidth derived.Based on the optimum bandwidth,the fiber grating filt... |
