Abstract
A laser module (,) comprises a Fabry-Perot cavity active element (,) with a facet (,) bearing an anti-reflection coating and an external cavity made by an optical fibre Bragg grating (,) with low reflectivity. This grating (,) presents a non-uniform profile of modulation of the refractive index, asymmetrical in the direction of the grating length, such as to give rise to a position of the equivalent mirror plane that is offset towards the end of the grating (,) that is closer to the active element (,).
