Abstract

Intense blue upconversion emission at 480nm has been obtained at room temperature in Tm3+:Nd3+ co-doped Ta2O5 channel waveguides fabricated on a Si substrate, when the sample is excited with an infrared laser at 793nm. The upconversion mechanism is based on the radiative relaxation of the Nd3+ ions (4F3/2 to 4I11/2) at about 1064nm followed by the absorption of the emitted photons by Tm3+ ions in the 3H4 excited state. A coefficient of energy transfer rate as high as 3 × 10-16 cm3/s has been deduced using a rate equation analysis, which is the highest reported for Tm-Nd co-doped systems. The confinement of the 1064nm emitted radiation in the waveguide structure is the main reason of the high energy transfer probability between Nd3+ and Tm3+ ions.
