CA 2055324

A laser is fabricated from an optical transmission medium having a laser cavity with an rare earth (e.g. Erbium) doped portion. At least one longitudinal mode is suppressed using a plurality of series coupled Fabry-Perot cavities, an optical grating, or a combination thereof. Ring lasers and linear structures are disclosed.

Un laser est fabriqué à partir d'un support de transmission optique doté d'une cavité laser ayant une partie dopé avec une terre rare (par exemple l'erbium). Au moins un mode longitudinal est supprimé grâce à plusieurs séries de cavités Fabry-Perot couplées, un réseau de diffraction optique ou une combinaison de ces éléments. Des lasers en anneau et des structures linéaires sont présentés.
