Nonlocal PMD compensation in the transmission of non-stationary streams of polarization entangled photons
We study the feasibility of nonlocally compensating for polarization mode
dispersion (PMD), when polarization entangled photons are distributed in
fiber-optic channels.We quantify the effectiveness of nonlocal compensation
while taking into account the possibility that entanglement is generated
through the use of a pulsed optical pump signal
Mitigation of inter-channel nonlinear interference in WDM systems
We demonstrate mitigation of inter-channel nonlinear interference noise
(NLIN) in WDM systems for several amplification schemes. Using a practical
decision directed recursive least-squares algorithm, we take advantage of the
temporal correlations of NLIN to achieve a notable improvement in system
performance
