Dynamic gain equalization based on electro-optic filtering in periodically-poled (LiNbO/sub 3/)

摘要

A cascade of electro-optically controlled filters in periodically-poled LiNbO/sub 3/ is used for dynamic gain equalization in DWDM systems. A dynamic gain equalizer with 3.2 dB insertion loss and >0.2 dB BER penalty was experimentally demonstrated.
