Wavelength Conversion with MZI-SOAs
T. Silveira; N. Yan; L. Oliveira; A. Teixeira; A. Ferreira; E. Tangdiongga; P. Monteiro; A.M.J. KoonenWavelength multicasting at 40Gb/s is demonstrated by all-optical multi-wavelength conversion based on a single MZI-SOA. Simultaneous ITU grid 200GHz spaced one-to-four conversion is achieved with negligible sensitivity difference among all the multicast channels. Furthermore, we propose some new all-optical applications enabled by this technology. ; Wavelength multicasting at 40Gb/s is demonstrated by all-opti...

Adaptive Chromatic Dispersion Compensation Using Electrical Transversal Filters
Luís M. R. Teixeira; Paulo M. N. P. Monteiro; Manuel Violas; António Teixeira; José Miguel SantosThis paper describes the possible use of electrical transversal filters as chromatic dispersion compensators in partially compensated light-wave systems. A particular case of a five-tap transversal filter is considered, and its performance evaluated based on the quality factor of the signal at the receiver.The bit-rates considered for computer simulations are 10Gbit/sand 40Gbit/s. ; This pa...
Orthotopic Liver Transplantation in Familial Amyloidotic Polyneuropathy Is Asso...
Ferreira, AC; Nolasco, F; Sampaio, S; Baptista, A; Pessegueiro, P; Monteiro, E; Barroso, EOrthotopic liver transplantation has become the treatment of choice for familial amyloidotic polyneuropathy. The aims of this study were to evaluate the renal complications post orthotopic liver transplantation in familial amyloidotic polyneuropathy and their impact. We retrospectively studied 185 recipients who underwent 217 orthotopic liver transplants. Mean age 36.8±9.5 years, 59% males, 14.3% with renal dys...
