Abstract

L'invention concerne un procédé de photoinscription d'un réseau de Bragg sur une fibre (300) ou un guide optique, dans lequel on procède à une étape d'exposition d'une zone choisie de la fibre (300) ou du guide avec un faisceau source (120)à l'aide d'un miroir (200) de manière à replier une partie (122) du faisceau source (120) réfléchie par le miroir (200) sur une partie (224) du faisceau source non réfléchie par la miroir et de manière à obtenir ainsi un réseau de diffraction sur la fibre (300) ou le guide, caractérisé en ce que l'on procède à une étape d'exposition supplémentaire sur cette partie de fibre (300) ou de guide, et en ce qu'on opère un déplacement relatif d'éléments parmi le fisceau (120), la fibre (300) ou le guide et le miroir (200) entre les deux étapes d'exposition, de telle façon qu'une même partie du faisceau (120) utilisée pour la photoinscription dans les deux étapes d'exposition, est réfléchie par le miroir (200) dans l'une des deux étapes et non réfléchir par le miroir (200) dans l'autre étape.
