Optical properties of Er3+-doped tungsten tellurite glass waveguides by Ag+-Na+ ion-exchange

摘要: Abstract The planar waveguides of 12Na2O · 35WO3 · 53TeO2 · 1Er2O3 glass (in mol%) were prepared by Ag+–Na+ ion-exchange at 300–360 °C for 5–30 h. effective mode indices and propagation losses the measured wavelengths 473, 632.8, 983.1 1548 nm means a prism coupler technique. waveguide depths from surface increased with increasing temperature time. diffusion parameters such as coefficient activation energy calculated on basis an Arrhenius dependence Ag+ ions in ion-exchanged glasses. 5.04–6.64, 2.70–4.77, 5.44–6.73 7.32–8.31 dB/cm first half distance 0 to 3.0 cm 3.52–4.82, 1.92–2.99, 3.78–5.06 3.91–5.15 dB/cm latter 1548 nm, respectively. relationship between optical properties conditions is discussed.
