The failure of a single optical link or node in a Wavelength Division Multiplexing (WDM) network may cause the simultaneous failure of several optical channels. In some cases, this simultaneity may make it impossible for the higher level (SONET or IP) to r ...
Hill et al. reported for the first time in 1978 the formation of refractive-index gratings in germanium doped silica fibers exposed to UV laser radiation. Since then many studies have been performed on fiber gratings and a widespread range of applications ...
This thesis presents new developments on the different intrinsic failure mechanisms of silica optical fibres and fibre Bragg gratings with regard to applications in the fields of telecommunications and metrology. These failure mechanisms are mainly due to ...
We propose a new configuration for semiconductor optical amplifiers (SOAs), called optical speed-up at transparency (OSAT), which allows to speed up the gain recovery of SOAs and their saturation power without sacrificing the gain, nor increasing the appli ...
Coherent optical beams are used to communicate, store, and process information in a growing number of applications. The availability of coherent laser sources is of critical importance for the realization of such optical information systems. An incoherent ...
We investigated the effect of the phase noise of fiber amplifiers on the linewidth of the amplified signal. We used three different sources as input signal, with linewidth between 5 kHZ and 18 GHz. We did not observe any spectral broadening of the signal l ...
Brillouin time-domain analysis in optical fibres is a novel technique making possible a distributed measurement of temperature and strain over long distance and will deeply modify our view about monitoring large structures, such as dams, bridges, tunnels a ...
In view of the laboratory tests performed at PSI with a Nafion tubular membrane reactor module for the catalysed methanol synthesis with CO2 and H-2 at 200 degrees C, the mechanical stability of a commercially available Nafion hollow fiber was tested at el ...
We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation. ...

A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM), the number of alarms and the difficul ...
