The present invention relates to the field of optical fiber telecommunications.
More specifically, the subject of the invention is a slanted Bragg grating optical
fiber and a process for manufacturing such a fiber. The slanted Bragg grating optical
fiber of longitudinal axis Z has slanted Bragg gratings photowritten in said fiber
and having refractive index modulations along said axis Z, inclined at a same writing
angle with respect to a normal plane to said axis Z and defining planes called
writing planes forming the same angle than the writing angle with said normal plane,
each writing plane forming with others writing planes specific angles called angles
of rotation about said axis Z.
