Photosensitive properties of a tin-doped sodium silicate glass for direct ultraviolet writing
In this letter, the fabrication of channel waveguides by direct UV writing into a bulk tin-doped multicomponent silicate glass is presented. Different laser powers and scan rates were employed and optimized to avoid surface ablation. The best results were obtained at a laser power of 95 mW and at a scan speed of 10 mm/min, where a refractive index change of 1.5×10–3 was estimated and an attenuation loss of 3.3 dB/cm was measured using the cutback method. A morphological investigation of the glass end facets was performed in order to assess the surface effect of the laser exposure.

Abstract

In this letter, the fabrication of channel waveguides by direct UV writing into a bulk tin-doped multicomponent silicate glass is presented. Different laser powers and scan rates were employed and optimized to avoid surface ablation. The best results were obtained at a laser power of 95 mW and at a scan speed of 10 mm/min, where a refractive index change of 1.5×10–3 was estimated and an attenuation loss of 3.3 dB/cm was measured using the cutback method. A morphological investigation of the glass end facets was performed in order to assess the surface effect of the laser exposure.
