A semiconductor laser element which can provide a good FFP free from ripple and close to a Gaussian distribution, and which is provided with a laminate structure that is formed by sequentially laminating a first conductive type semiconductor layer, an active layer, and a second conductive type (different from the first conductive type) semiconductor layer and that has a waveguide area for guiding light in one direction and a laser-resonating resonator surfaces at the opposite ends thereof, wherein the laminate structure has at one end thereof a non-resonator surface separate from the resonator surfaces and formed so as to include an active layer sectional surface, and the active layer sectional surface of the non-resonator surface is covered with a light shielding layer.

L'invention concerne un élément laser à semi-conducteurs permettant d'obtenir un bon FFP (laser à fibres Fabry-Pérot) sans fluctuations et proche d'une distribution gaussienne. Cet élément laser comprend une structure stratifiée formée par stratification séquentielle d'une première couche semi-conductrice de type conductrice, d'une couche active et d'une seconde couche semi-conductrice de type conductrice (différente de la première couche), une zone guide d'ondes permettant de guider la lumière dans une direction et des surfaces résonnantes d'un laser à résonance situées au niveau des extrémités opposées du guide d'ondes. La structure stratifiée comprend, à une de ses extrémités, une surface non résonnante séparée des surfaces résonnantes, formée de façon à inclure une surface en coupe de la couche active, la surface en coupe de la couche active de la surface non résonnante étant recouverte par une couche de protection contre la lumière.
