摘　　要：利用YVO4双折射晶体 ,设计了一种新型光通讯密集波分复用 (DWDM)系统波长监控的方案 ,分析了其工作原理 ,并对方案的可行性进行了实验研究。理论和实验结果均表明 ,这种方案能够用于整个C波段的DWDM系统工作波长监控与锁定。这种方案与使用F P标准具的透射谱进行波长监控的方法相比 ,具有标准工作波长容易判定。By using the birefringent crystal YVO_4, a novel scheme of wavelength monitoring in DWDM optical communication systems is presented. The principle of this scheme is analyzed and its feasibility is inspected with experiments. Theoretical analysis and experimental results both show that it can be applied in C-band wavelength monitoring and locking in DWDM systems. As compared with the method of wavelength monitoring by means of the transmission spectrum of a Fabry-Perot etalon, this scheme has advantages such as easy judgment of normal operation wavelengths, high sensitivity of monitoring and easy integration.
