CA 2212736

A laser comprising first and second feedback elements defining a laser cavity, and a gain medium within the laser cavity, the gain medium having first and second facets (5, 6) and an optical waveguide (8) for guiding optical radiation between said first and second facets, wherein the second feedback element is wavelength selective, and the optical waveguide (8) is configured to direct optical radiation at an angle .theta. to the normal of the second facet (6).

Laser qui comprend des premier et second éléments de rétroaction définissant une cavité de laser, et un milieu de gain à l'intérieur de ladite cavité, ledit milieu de gain ayant des première et seconde facettes (5, 6) et un guide d'ondes (8) destiné à guider un rayonnement optique entre lesdites première et seconde facettes. Le second élément de rétroaction est sélectif par rapport aux longueurs d'ondes et le guide d'ondes (8) optique est configuré pour diriger des rayonnements optiques à un angle .theta. par rapport à la perpendiculaire de la seconde facette (6).
