It has been demonstrated that B containing glasses are sensitive to radiation in the band 225-275 nm and, therefore, B2O3 glasses are particularly adapted to receive refractive index modulation, e.g., to make reflection gratings. Glasses containing SiO2 and B2O3, are particularly suitable when the grating is to be localised in the cladding of a fibre. Glasses containing SiO2, GeO2 and B2O3 are suitable when the grating is in the path region of a waveguide, e.g., in the core of a fibre.
