摘　　要：对三种不同结构的光纤光栅和环形器组成的光分插复用器的同频串扰进行了实验研究。实验表明 ,与常规的Ⅰ型结构光分插复用器相比 ,Ⅱ型和III型结构中由上载端泄漏到下载端的同频串扰分别减少了 2 4.4dB和39.3dB ,由下载端泄漏到上载端的同频串扰分别减少了 2 3 .6dB和 2 4.6dB。Three kinds of add-drop multiplexers (OADMs) based on fiber gratings and circulators are proposed and demonstrated. There is significant homodyne crosstalk reduction of about 24.4 dB, 39.3 dB and 23.6 dB, 24.6 dB on the dropped and added channels, respectively, for the best proposed II-type structure and III-type structure as compared with the conventional I-type structure.
