Abstract

We studied fibre Bragg grating fabrication in Ge/B codoped photosensitive fibre using high-intensity (60-230 GW cm^-2) 264 nm, 220 fs laser pulses The ratio of the refractive index modulation to the incident fluence was found to be independent of the irradiation intensity which points to a single-quantum mechanism of Bragg grating fabrication under the stated experimental conditions.
