Pj. Hughes et al., Optical characteristics of photosensitive Ge-doped SiO2 planar waveguides implanted with protons at 800 degrees C, ELECTR LETT, 36(5), 2000, pp. 427-428
An experimental study of the absorption, refractive index and UV photosensi
tivity of proton implanted Ge-doped planar glass waveguides has shown that
the defects induced by implantation at 800 degrees C were photobleached aft
er UV exposure and that self-annealing occurred.
