Large photo-induced refractive index changes in pulsed laser deposited lead germanate glass waveguides with controllable refractive index sign change

Large photo-induced refractive index changes in pulsed laser deposited lead germanate glass waveguides with controllable refractive index sign change
Large photo-induced refractive index changes in pulsed laser deposited lead germanate glass waveguides with controllable refractive index sign change
Photosensitive lead germanate glass optical waveguides have been grown by pulsed laser deposition. The deposited waveguides are photosensitive over a broad ultraviolet spectral range (325 nm 193 nm). Positive and/or negative refractive index changes have been observed depending on the intensity of the ultraviolet radiation as well as on the deposition conditions. Absolute refractive index change values up to |Δ n|=1.06 x 10-2 have been measured.

Abstract

Photosensitive lead germanate glass optical waveguides have been grown by pulsed laser deposition. The deposited waveguides are photosensitive over a broad ultraviolet spectral range (325 nm 193 nm). Positive and/or negative refractive index changes have been observed depending on the intensity of the ultraviolet radiation as well as on the deposition conditions. Absolute refractive index change values up to |Δ n|=1.06 x 10-2 have been measured.
