The fabrication of microcavities by rf-sputtering process and their optical properties are described. The cavity is constituted of an Er3+/Yb3+-codoped SiO2 active layer inserted between two Bragg mirrors, fabricated by stacking alternately five TiO2 and Er3+/Yb3+-activated SiO2 films fabricated by rf-sputtering. NIR Transmission spectra were performed. The cavity resonance with a quality factor of 70 was obtained at 1528 nm. Er3+ luminescence modification due to the cavity effect, intensity enhancement and modification of the line shape has been observed.
