A Parametric Gain Approach to Performance Evaluation of DPSK/DQPSK Systems with Nonlinear Phase Noise

P. Serena, A. Orlandini, A. Bononi

Optical Communication Theory and Techniques > Characterizing, Measuring, and Calculating Performance in Optical Fiber Communication Systems > 129-136

We present a novel method based on parametric gain (PG) to study the impact of nonlinear phase noise in dispersion-managed differentially phase-modulated optical transmission systems. By linearizing the interaction of signal and noise, the received ASE is approximated as a stationary Gaussian process, whose statistics are found by using a low-pass filtered version of the modulating signal. The BER...

Regeneration savings in flexible optical networks with a new load-aware reach maximization

A. Bononi, P. Serena, A. Morea, G. Picchi

Optical Switching and Networking > 2016 > 19 > P3 > 123-134

We propose and analyze a new load-aware reach maximization procedure based on the Gaussian Noise model for dispersion-uncompensated optical networks with coherent detection. We estimate the opto-electronic regeneration savings with respect to the standard full-load reach approach, and find examples where significant savings can be achieved. The load aware reach and its corresponding optimal power...

2015 Tyrrhenian International Workshop on Digital Communications (TIWDC)

We provide an analytical expression of the nonlinear phase induced by the Kerr effect that highlights its dependence on the modulation format and on the link parameters. We show that such a nonlinear phase must be used in regular-perturbation models in order to minimize their modeling error. We detail the case of dispersion-managed systems as an application example.

Journal of Materials Science: Materials in Electronics > 2012 > 23 > 4 > 817-824

Epoxy thin film composites filled with particulate nanofillers; synthetic diamond and graphene nanoplatelets were prepared and characterized based on tensile, thermal, and electrical properties. The influences of these two types of fillers, especially in terms of their loading, sizes and shapes, were discussed. It was found that the epoxy thin film composites incorporating synthetic diamond displayed...

We investigate the interaction between Kerr nonlinearity and polarization mode dispersion (PMD) in homogeneous multi-channel polarization division multiplexing coherent phase shift keying transmissions. Assuming linear distortions can be fully equalized by the coherent receiver, we concentrate the investigation on the residual nonlinear penalty. We introduce a novel simulation procedure to discriminate...
