Characterization and Modelling of Timing Jitter in an Optical Soliton Source Ba...
Jorge R. A. Pinto; Tiago N. G. Maia; A. Nolasco Pinto; Rui S. RibeiroIn this paper the output timing jitter of a solitonsource, based on the gain-switching technique of asemiconductor laser, is analysed. A laboratorial timing jittermeasurement, at the laser output, is initially performed,followed by the identification of its origins. Aftercharacterizing the laser noise and the electrical signal, usedto pulsate the laser, a numerical model is developed in orderto be used in the s...
Performance Degradations due to Crosstalk in Multiwavelength Optical Networks U...
P. S. André; J. L. Pinto; A. Nolasco Pinto; T. AlmeidaThe impact of homodyne and heterodyne crosstalk on an optical signal passing through an optical add drop multiplexer (OADM) node in dense wavelength division multiplexing (DWDM) network is studied, and the analytical expressions for the power penalty are obtain. The statistical impact of crosstalk on signal is studied by simulation and the results compared with experimental data. ;...
