Abstract

We report on the observation of confocal micro-luminescence originated by defects created in direct UV written silica-on-silicon waveguides. Spatial and spectral analysis of the visible luminescence bands was performed with 488nm excitation. This has revealed the UV formation of different defects which are related to the different compositions of core and cladding layers.
