Wideband delays generated in an all-optical tunable delay line, preserving signal wavelength and bandwidth
[Retards à grande bande passante engendrés dans une à ligne à retard tout-optique accordable, préservant la longueur d'onde et la bande passante du signal]
Comptes Rendus. Physique, Volume 10 (2009) no. 10, pp. 1008-1013.

Une nouvelle technique pour produire des grands retards ajustables et contrôlés de manière tout-optique, cesi pour un train d'impulsions de 100 ps dans des fibres optiques, est ici démontrée. La ligne à retard est réalisée par la combinaison de deux fonctions principales : une conversion de longueur d'onde via des amplificateurs optiques à semi-conducteurs et un retardement du signal via un milieu optique dispersif. Le signal converti en longueur d'onde a été retardé avec précision par propagation dans une fibre dispersive sur une échelle temporelle allant de la picoseconde à quelques nanosecondes, en conservant la longueur d'onde et la bande passante du signal. Des impulsions de 100 ps ont été retardé continûment jusqu'à 14 ns avec une distorsion réduite, correspondant à un retard séquentiel de 140-bits.

A novel technique to produce large all-optically controlled tunable delays of 100 ps pulse train in optical fibers is demonstrated. The configuration of the delay line basically consists of two main stages: the wavelength conversion via semiconductor optical amplifiers and the group velocity delaying via a dispersive optical medium. The wavelength-converted signal was precisely delayed over a wide temporal range from picoseconds to nanoseconds using a dispersive fiber, preserving the wavelength and the bandwidth of the signal. 100 ps FWHM signal pulses were delayed continuously up to 14 ns with moderate pulse distortion, corresponding to a 140-bit delay.
