Patent

CA 2092589

An article, such as an optical communication system, which includes a laser formed in an optical waveguide or optical fiber having a rare-earth-doped core or core portion. In one embodiment, the optical resonant cavity of the laser is at least partially defined by a distributed Bragg reflector (10, 20) formed in a portion of the core. In contrast to the prior art, the length of the optical resonant cavity is about 5 cm or less.

L'invention est un article, tel qu'un système de communication optique, qui comprend un laser formé dans un guide de lumière ou une fibre optique dont l'âme ou une partie de l'âme est dopée avec une terre rare. Dans l'une des concrétisation de l'invention, la cavité résonante optique du laser est définie au moins partiellement par un réflecteur de Bragg réparti (10, 20) formé dans une partie de l'âme. Contrairement à ce que l'on trouve dans l'état actuel de la technique, la longueur de la cavité résonante optique est de 5 cm ou moins.
