Abstract

We report very large photoinduced refractive-index changes Δn, of the order of 102, 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 to 244-nm light through a phase mask, whereas the sign of Δn was determined from ellipsometric data. Results are shown for films grown under oxygen pressures ranging from 1×10-2 to 6×10-2 mbars 1.33 mbars=1 Torr.
