Luminescent Ions in Silica-Based Optical Fibers
Bernard Dussardier, Wilfried Blanc, Gérard Monnom
We present some of our research activities dedicated to doped silica-based optical fibers, aiming at understanding the spectral properties of luminescent ions, such as rare-earth a…
Role of CaO addition in the local order around Erbium in SiO2 ?GeO2 ?P2O5 fiber preforms
Francesco D'Acapito, Chiara Maurizio, M. C. Paul +3
The development of materials for optical signal processing represents a major issue in present technology. In this contribution we present a study on Er-doped fiber preforms where…
Thulium environment in a silica doped optical fibre
Wilfried Blanc, Thomas Lee Sebastian, Bernard Dussardier +4
Thulium-doped optical fibre amplifiers (TDFA) are developed to extend the optical telecommunication wavelength division multiplexing (WDM) bandwidth in the so-called S-band (1460-1…
Cavity Soliton Laser based on mutually coupled semiconductor microresonators
Patrice Genevet, Stéphane Barland, Massimo Giudici +1
We report on experimental observation of localized structures in two mutually coupled broad-areahttp://hal.archives-ouvertes.fr/images/calendar.gif semiconductor resonators. These…
Optical Scar in a chaotic fibre
Valérie Doya, Olivier Legrand, Claire Michel +1
We propose to use a multimode optical fiber with a D-shaped cross section as a privileged system to image wavefunctions of a chaotic system. Scar modes are in particular the sub je…
Multiplicative noise in the longitudinal mode dynamics of a bulk semiconductor laser
F. Pedaci, S. Lepri, S. Balle +3
We analyze theoretically and experimentally the influence of current noise on the longitudinal mode hopping dynamics of a bulk semiconductor laser. It is shown that the mean reside…
