The nonlinear refractive index has drawn considerable attention these past few years, because it may significantly perturbate long-range propagation of lightwaves in optical fibers. Two main origins to this nonlinearity have been identified: nonresonant el ...
We report the first demonstration of an extremely simple and efficient 1.24 μm phosphosilicate fiber-based Raman laser with Bragg gratings written directly in the fiber used. The laser pumped by Nd fiber laser exhibits a slope efficiency of 80% ...
A single failure in a communication network may trigger many alarms. When the communication network uses optical fibres as a transmission medium and increases its capacity by using Wavelength Division Multiplexing (WDM) and Space Division Multiplexing (SDM ...
A novel measurement scheme is presented for injection locking experiments with semiconductor lasers. In the method, the light generated by the master laser travels through an optical fiber before being injected into the cavity of the slave laser. Using the ...
A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
Piezoelectric ZnO coatings on optical fibers are of interest for active optical-fiber devices such as phase and wavelength modulators. Reactive magnetron sputtering has been used to prepare high-resistivity [001] radially oriented ZnO coatings on 85 mm lon ...
A novel surveillance system for installed fiber optic cables is presented. It is based on the analysis of the local stimulated Brillouin scattering interaction. The configuration of the instrument rely on the use of a single laser source and the required l ...
Among all non-linear optical effects observed in single-mode optical fibres, stimulated Brillouin scattering (SBS) is of particular importance since it has numerous practical implications. SBS occurs when laser waves are scattered through the interaction o ...
One goal of the QUELL experiment is the validation of numerical codes for the simulation of thermo-hydraulic transients in Cable-in-Conduit Conductors with Central Channel (C-5). The validation of Gandalf has focused on 17 quench propagation runs. In gener ...
A new class of active fiber devices based on piezoelectric coated optical fibers is currently being developed. The piezoelectric coating is used to produce acoustic waves within the optical fiber and these acoustic waves interfere with optical signals pass ...
