摘要：
Photosensitive lead germanate glass optical waveguides have been grown by pulsed laser deposition. The deposited waveguides are photosensitive over a broad ultraviolet spectral range (325–193 nm). Positive and/or negative refractive index changes have been observed, depending on the intensity of the ultraviolet radiation as well as on the deposition conditions. Absolute refractive index change values up to |Δn|=1.06×10-2 have been measured.
