Er-doped silica-based waveguides prepared by different techniques: RF-sputtering, sol-gel and ion-exchange
(Kluwer Academic Publ, 2002-12-01)
Erbium-activated silica-based planar waveguides were prepared by three different technological routes: RF-sputtering, sol-gel and ion exchange. Various parameters of preparation were varied in order to optimize the waveguides ...

Enhanced frequency upconversion in Er3+ doped fluoroindate glass due to energy transfer from Tm3+
(2002-12-01)
Energy transfer processes between Er3+ and Tm3+ were investigated examining the frequency upconversion emissions in a fluoroindate glass pumped at 790 nm. A 60-fold enhancement in the emission at ≈670 nm originating from ...
Erbium-activated HfO2-based waveguides for photonics
(Elsevier B.V., 2004-03-01)
Silica-based sol-gel waveguides activated by Er3+ ions are attractive materials for integrated optic devices. 70SiO(2)-30HfO(2) planar waveguides, doped with Er3+ concentrations ranging from 0.01 to 4 mol%, were prepared ...

Er rare-earth ion incorporation in sol-gel SnO2
(ABM, ABC, ABPol, 2003-12)
Er-doped SnO2 thin films and xerogels are obtained by sol-gel technique. In order to understand the Er³+ rare-earth ion activity in SnO2 matrix, a characterization of Er incorporation is done through emission and excitation ...
