Abstract (en)
[origin: WO03087906A1] The invention relates to a method for production of an optical filter, characterised in comprising the following operation steps on an optical guide (10): a control operation on the expanding internal shape of the guide, preferably by fusion drawing and the etching of a Bragg grating (20), using methods which permit an independent control of both the longitudinal variation of the Bragg wavelength and the longitudinal variation in external profile of the guide.
