Abstract
Photosensitive lead germanate glass optical waveguides have been grown by p ulsed laser deposition. The deposited waveguides are photosensitive over a broad ultraviolet spectral range (325-193 nm). Positive and/or negative ref ractive index changes have been observed, depending on the intensity of the ultraviolet radiation as well as on the deposition conditions. Absolute re fractive index change values up to \Delta n\ = 1.06 x 10(-2) have been meas ured.
