When measuring very low differential group delay (DGD), standard techniques are affected by rather high uncertainties. This problem is usually solved by repeating many times the DGD measurements while randomly perturbing the fiber. Such an approach i

The application of a reduced variational formalism, to model guided-wave optical signal processing devices is reviewed. The focus is mainly on second-order non-linearities. First, approximate analytical solutions (solitary waves) are derived for prop

We report polarization mode dispersion measurements on a 168 km long undersea optical cable, performed with two techniques. From experimental results, statistical behavior of polarization parameters and their time fluctuations have been extracted. An

Previous results indicate that fibers in ribbons are sometimes affected by systematic birefringence superimposed on the random one, their relative weights depending on fiber position in the ribbon. We report new theoretical and experimental results o

The work focuses on periodically poled lithium niobate crystals grown by the off-center Czochralski technique and exhibiting an appreciable second harmonic generation efficiency. Several samples have been characterized through experimental measuremen

We discuss the application of the bidirectional beam propagation method for the analysis of nonlinear microstructured waveguides. We review two different formulations of the nonlinear algorithm, and demonstrate, also by comparison with experimental d

Recent results provided experimental evidence that losses in bent Ti:LiNbO/sub 3/ waveguides can be drastically reduced by using additional titanium and magnesium oxide. We determine an optimization procedure for the index profile in curved sections.

First-order polarization-mode dispersion (PMD) compensation by means of a polarization controller and a differential delay line is not sufficient to guarantee error-free transmission for 40-Gb/s channels when higher order effects severely increase si

Cables where several fibers (typically, 4-16) are collected in a ribbon allow cost reduction and mass splicing. Their wide use in the access network and, in perspective, in long-haul links, has drawn attention on all factors affecting their performan

The dynamics of a two-dimensional optical beam propagating in a nonlinear channel waveguide is investigated by means of a variational technique. Through this analysis, one can determine the eigenmodes (self-trapped modes) of the structure. Their stab
