Controlling the delay of 100 Gb/s polarization division multiplexed signals through silicon photonics delay lines

摘要

We show a direct comparison between silicon reconfigurable delay lines based on coupled resonator optical waveguides and photonic crystal waveguides. The structures are used to selectively delay the two orthogonally polarized channels of a RZ-PolDM-DQPSK format at 100 Gbit/s.
