Abstract :
A germanosilicate fibre (7 mol.% GeO2) codoped with nitrogen has been fabricated by the surface plasma CVD process. The fibre has demonstrated a photoinduced refractive index change of 2×10-3 at an irradiation dose of 75 kJ/cm2 and a wavelength of 244 nm without hydrogen loading, and an index change of 1×10-2 after hydrogen loading
