The invention provides a method of manufacturing a chirped optical fiber grating, the method comprising the steps of an etching the cladding of the optical fiber to vary the cross-sectional area of a portion of an optical fiber, and impressing a grating of uniform pitch on the portion of the fiber in which the portion of the fiber is subjected to different respective longitudinal forces du'ing the impressing step and during subsequent use of'the grating.
Un procédé de fabrication d'un réseau de diffraction à fibres optiques modifié par déformation (chirped), consiste à: attaquer chimiquement le gainage de la fibre optique de sorte que la section d'une partie de celle-ci soit modifiée; à imprimer un réseau de diffraction à espacements réguliers sur ladite partie de la fibre, laquelle est soumise à différentes forces longitudinales respectives pendant la phase d'impression et l'utilisation ultérieure dudit réseau.
