Title
(EN) OPTICAL GRATING WRITING SYSTEM
(FR) SYSTEME OPTIQUE DE GRAVURE DE RESEAUX
Abstract
(EN)
An interferometer (100) for writing Bragg gratings comprising the means for splitting (112) a light beam (114) into two coherent beams (116, 118), and a first optical lens arrangement (106, 108, 110) for bringing the coherent beams to interference for writing the Bragg grating in a photosensitive material (122). The first optical lens arrangement is arraged, in use, to vary an angle $g(b) between the two interfering beams.
(FR)
L'invention concerne un interféromètre (100) permettant de graver des réseaux de Bragg. Cet interféromètre comporte un dispositif servant à séparer (112) un faisceau lumineux (114) en deux faisceaux cohérents (116, 118), et un dispositif à première lentille optique (106, 108, 110) servant à amener les faisceaux cohérents en interférence pour graver les réseaux de Bragg sur un matériau photosensible (122). Le dispositif à première lentille optique est configuré, pendant la marche, pour faire varier un angle $g(b) entre les deux faisceaux interférents.
