A simple digital skew compensator for coherent receiver

A simple digital skew compensator for coherent receiver

A skew compensator is proposed and experimentally demonstrated for coherent front-end, which improved tolerance from plusmn3 to plusmn21 ps at 0.2 dB Q-penalty even with 21,000 ps/nm CD and 90 ps DGD on 112 Gb/s DP-QPSK receiver.
