Abstract

A method of manufacturing a chirped optical fibre grating comprises the steps of: etching the cladding of the optical fibre to vary the cross-sectional area of a portion of an optical fibre; and impressing a grating of uniform pitch on the portion of the fibre; in which the portion of the fibre is subjected to different respective longitudinal forces during the impressing step and during subsequent use of the grating.
