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. Finally, results concerning Er3+-activated opal-based photonic crystal are presented. In the case of inverted opals a quantum efficiency of 90% was estimated

Abstract
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. Finally, results concerning Er3+-activated opal-based photonic crystal are presented. In the case of inverted opals a quantum efficiency of 90% was estimatedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
