Photosensitivity of lead germanate glass waveguides grown by pulsed laser deposition
We report very large photoinduced refractive index changes, Δn, of order ~10<sup>-2</sup>, in lead germanate glass waveguides grown by pulsed laser deposition. The magnitude of Δn was derived from measurements of diffraction efficiency for gratings written by exposure with 244 nm light t...
