Un système de détection optique utilisant un laser DFB à très petite ouverture est théoriquement proposé. Le niveau de gain seuil dans le laser DFB varie de manière sensible avec les réflexions combinées par la facette et l'ondulation ainsi qu'avec l'injection optique réfléchie à la surface du disque optique. La variation du niveau de gain seuil est comptée comme le changement de tension sur les électrodes du laser. On constate que la sensibilité de la détection optique avec un laser DFB bien conçu devient six fois plus grande que celle des lasers Fabry-Perot conventionnels. La distribution du champ autour de la petite ouverture est analysée en tenant compte à la fois du champ proche et du champ de rayonnement. Des données numériques sur le changement de tension sont données à titre d'exemples du système de détection.

Abstract: An optical detection system using a DFB laser with a very small aperture is theoretically proposed. The threshold gain level in DFB laser is sensitively varied with combined reflections by the facet and the corrugation as well as with the optical injection reflected at the surface of the optical disk. Variation of the threshold gain level is counted as the voltage change on electrodes of the laser. It is found that sensitivity of the optical detection with a well-designed DFB laser becomes six times larger than that with conventional Fabry-Perot ones. Field distribution around the small aperture is analyzed taking into account both the near-field and the radiation field. Numerical data on the voltage change are given as examples of the detection system.
