Simultaneous PMD mitigation by optically clocked reshaper for two-channel 80-Gbit/s RZ-DQPSK signals

Simultaneous PMD mitigation by optically clocked reshaper for two-channel 80-Gbit/s RZ-DQPSK signals has been demonstrated using gain saturation effects of optical parametric amplification. The reshaper was applied to mitigate DGD as high as 100 ps.
