The structural and photoluminescence properties of ytterbium-erbium silicate thin films have been investigated. The films were fabricated by RF-magnetron co-sputtering of Er2O3, Yb2O3 and SiO2 on c-Si and subsequent annealing in N2 or O2 atmosphere.
[Show abstract][Hide abstract] ABSTRACT: The photoluminescence (PL) and decay time at 1.53μm of sputtered Er0.2Re1.8Si2O7 (Re=Yb, Y) thin films were investigated. The enhancement of the PL at 974nm pumping in the Er0.2Yb1.8Si2O7 film was demonstrated compared with Er0.2Y1.8Si2O7 film.
[Show abstract][Hide abstract] ABSTRACT: We first fabricated the hybrid Si3N4-Er/Yb/Y silicate waveguide amplifiers, and the internal gain of 1.25dB/cm with gain bandwidth of 20nm was observed using 1476nm pumping.

[Show abstract][Hide abstract] ABSTRACT: Photoluminescence quantum efficiency and energy transfer were studied in ErRE (RE = Y, Yb) silicate thin films. For the first time, we experimentally determined the radiative/non-radiative decay rates of ErYb and ErY silicates and obtained photoluminescence quantum efficiencies of 0.28 ± 0.08 and 0.39 ± 0.13, respectively. Energy transfer between Yb and Er in ErYb silicate was investigated by comparing the effective excitation cross sections of ErYb and ErY silicate. At different pumping wavelengths, forward and backward energy transfer caused by the presence of Yb was experimentally demonstrated.
