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
UV induced refractive index changes in lead germanate glass waveguides grown by pulsed laser deposition
We report very large photoinduced refractive index changes Delta.n, of order ~10-2, in lead germanate glass waveguides grown by pulsed laser deposition. The magnitude of Delta.n was derived from measurements of diffraction efficiency for gratings written by exposure with 244 nm light through a phase mask, while the sign of Delta.n 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 Delta.n, of order ~10-2, in lead germanate glass waveguides grown by pulsed laser deposition. The magnitude of Delta.n was derived from measurements of diffraction efficiency for gratings written by exposure with 244 nm light through a phase mask, while the sign of Delta.n 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.
