Confocal luminescence investigations of two-beam direct-uv-written silica-on-silicon waveguides
Two-beam direct-UV-written silica-on-silicon waveguides have been investigated by confocal micro-luminescence experiments. The spatial and spectral analysis of the visible luminescence observed after 488 nm excitation has revealed the presence of various UV-induced defects due to the different compo...
