Abstract

Chalcogenide optical glass is an interesting material, for both fibre and planar technologies, as it offers possibilities for a wide array of devices suitable for use in both non-linear applications and as IR sources. Channel waveguide structures were directly written into bulk gallium lanthanum sulphide glass via above-bandgap (lambda=244nm) illumination. Focused fluence of 1.5-150J/cm2 from a UV-laser was applied, inducing giant-photocompaction and photochemical changes. A typical channel waveguide had attenuation <0.3dB cm-1 and was spatially single-mode at 1µm. The damage threshold for fabricating such devices in this glass system is also discussed.
