Abstract

Dynamic DWDM channel blocking and equalizing is proposed based on liquid crystal (LC) and bulk grating technology. A dispersion compensation and enhancement unit is employed so that low center-frequency shift small footprint could be achieved at the same time. The inter-channel crosstalk is also studied. With the optimized design of dispersion unit and LC module, a 32-channel, 100-GHz spacing sample is demonstrated with the insertion loss (IL) of 5.5 dB and 45dB extinction ratio. Application of our device to reconfigurable optical add-and-drop (ROADM) network is discussed
