  ABSTRACT: We demonstrate a fast-speed PMDC for 40 Gb/s DBPSK and DQPSK. The PMDC increases tolerable average PMD of the DBPSK and DQPSK system to 9 ps and 18 ps, respectively.

• Conference Proceeding: Dynamic Performance Evaluation of Optical Polarization Mode Dispersion Compensators and Electronic Equalizers Including Forward Error Correction

  ABSTRACT: A method to test the dynamic performance of polarization mode dispersion (PMD) compensators (PMDCs) is presented. The dynamic performance of an optical PMDC combined with electronic equalizers is measured before and after forward error correction.

• Article: Optimum length of one-stage polarization-mode dispersion compensators with a fixed delay line

  [show abstract] [hide abstract]
  ABSTRACT: We investigate the performance of the one-stage polarization-mode dispersion (PMD) compensator with a fixed delay line. We find that there exists an optimum delay line length for the PMD compensator and the optimum delay line length decreases with the increase of signal bandwidths. We show that such PMD compensators, when optimized, can achieve almost the same performance as that achieved by those with a variable delay line.

• Article: Comparison of system tolerance to polarization-mode dispersion between different modulation formats

  Chongjin Xie, L. Moller, H. Haunstein, S. Hunsche
  [show abstract] [hide abstract]
  ABSTRACT: The polarization-mode dispersion (PMD) tolerance of different modulation formats is studied, including ON-OFF keyed (OOK), differential phase-shift keyed (DPSK), and carrier-suppressed return-to-zero (CSRZ) formats. It is shown that, generally, for PMD uncompensated systems, the modulation formats with larger pulsewidth have larger penalty, while the modulation formats with smaller bandwidth perform better in PMD compensated systems. It is also shown that DPSK can tolerate more PMD than OOK for both PMD uncompensated and compensated systems, and that CSRZ, because of its specific spectrum characteristics, has a different feature from return-to-zero formats.

  Article: Higher order PMD distortion mitigation based on optical narrow bandwidth signal filtering

  L. Moller, J.H. Sinsky, H. Haunstein, S. Chandrasekhar, C.R. Doerr, J. Leuthold, C.A. Burrus, L.L. Buhl
  [show abstract] [hide abstract]
  ABSTRACT: We show a novel higher order polarization-mode dispersion (PMD) mitigation technique for a preamplified system based on narrow optical bandwidth filtering of the signal. Reducing the signal bandwidth results in increased signal immunity against higher order PMD distortions. The method is theoretically explained and experimentally verified.

• Conference Proceeding: Novel higher order PMD distortion mitigation technique for RZ signals

  [show abstract] [hide abstract]
  ABSTRACT: We have demonstrated that optical narrow bandwidth filtering of RZ signals can reduce pulse distortions that result from higher order PMD. The required filter bandwidth is significantly smaller than conventional filter rules predicted for optimal detection in the case of no PMD. Advantageously, this higher order PMD mitigation method requires no active channel adaptation, only a passive filter.
