CA 2431770

A Bragg Grating optical waveguide laser source comprising at least one Bragg grating in a rare earth doped waveguide and an optical pump source coupled to said doped waveguide, said Bragg gratings having at least two different peak reflection wavelengths and at least one of said Bragg gratings comprising a phase-shift and a phase-shift actuator being coupled to the phase-shift for controlled application of changes in the phase-shift thus activating or deactivating the corresponding Bragg grating waveguide laser.

L'invention concerne une source laser en guide d'ondes optique à réseau de Bragg, qui comprend au moins un réseau de Bragg dans un guide d'ondes dopé aux terres rares et une source de pompe optique couplée audit guide d'ondes dopé. Les réseaux de Bragg présentent au moins deux longueurs d'onde de réflexion de crête différentes, et au moins un des réseaux de Bragg comprenant un décalage de phase et un actionneur de décalage de phase couplé au décalage de phase pour une application régulée de modifications du décalage de phase, ce qui active ou désactive le laser en guide d'ondes à réseau de Bragg correspondant.
