In this paper, we present a short review of the activity performed in developing glass-based photonic structures on the nano and micro scale, based on the sol-gel techniques and activated by rare earth ions. Optical and spectroscopic assessment of glass ceramic waveguides is discussed. Luminescence enhancement is demonstrated. Refractive index modulation upon UV exposure is measured in SiO2-SnO2 film...
The aim of this lecture is to highlight some advances in erbium-activated silica-based photonic systems, where suitable geometries and appropriate fabrication protocols allow tailoring and enhancement of optical and spectroscopic properties. In particular, the following topics are presented: (i) rare earth-activated glass ceramics planar waveguides; (ii) Er3+-activated Ag exchanged silicate glass;...
