Abstract

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.
