Digital backpropagation accounting for polarization-mode dispersion.
Digital backpropagation (DBP) is a promising digital-domain technique to mitigate Kerr-induced nonlinear interference. While it successfully removes deterministic signal-signal interactions, the performance of ideal DBP is limited by stochastic effects, such as polarization-mode dispersion (PMD). In this paper, we consider an ideal full-field DBP implementation and modify it to additionally acc...
متن کاملPolarization-Mode Dispersion Aware Digital Backpropagation
We study a modified DBP algorithm that accounts for PMD. Based on the accumulated PMD at the receiver, the algorithm distributively compensates for PMD in the reverse propagation and outperforms the conventional approach by up to 2.1 dB.
متن کاملEvaluation of Polarization Mode Dispersion and Chromatic Dispersion using Quantum Interferometry
The use of quantum correlations between photons to measure polarization mode dispersion (PMD) and chromatic dispersion is investigated. Two types of apparatus are discussed which use coincidence counting of entangled photon pairs to allow sub-femtosecond resolution for measurement of both PMD and chromatic dispersion, as well as separation of even-order and odd-order chromatic effects in the PM...
متن کاملSimultaneous chromatic dispersion, polarization-mode-dispersion and OSNR monitoring at 40Gbit/s.
A novel method for independent and simultaneous monitoring of chromatic dispersion (CD), first-order PMD and OSNR in 40Gbit/s systems is proposed and demonstrated. This is performed using in-band tone monitoring of 5GHz, optically down-converted to a low intermediate-frequency (IF) of 10kHz. The measurement provides a large monitoring range with good accuracies for CD (4742+/-100ps/nm), differe...
متن کاملPolarization mode dispersion compensation of chirped Bragg gratings used as chromatic dispersion compensators
Compensation of Polarization Mode Dispersion (PMD) induced by a chirped Bragg grating is performed using a short length of highly birefringent fiber. A recirculating loop experiment demonstrates complete PMD compensation of the chirped Bragg grating. This simple method can be extended to deterministic PMD compensation of any components. Introduction: Pulse broadening induced by PMD is now an im...
