UV induced refractive index changes in lead germanate glass waveguides grown by pulsed laser deposition
UV induced refractive index changes in lead germanate glass waveguides grown by pulsed laser deposition
We report very large photoinduced refractive index changes Δn, of order ~10-2, 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 through a phase mask, while the sign of Δn was determined from ellipsometric data. Results are shown for films grown under oxygen pressures ranging from 1 x 10-2 to 6 x 10-2 mbar.

Abstract
We report very large photoinduced refractive index changes Δn, of order ~10-2, 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 through a phase mask, while the sign of Δn was determined from ellipsometric data. Results are shown for films grown under oxygen pressures ranging from 1 x 10-2 to 6 x 10-2 mbar.
