Abstract

Starting from the measured parameters of multilayer microcavities activated by Er3+ ion, we developed a comprehensive model based on extended (3 x 3) transfer matrix formalism including sources. The cavity, fabricated by rf-sputtering technique, was constituted by an Er3+-activated SiO2 active layer inserted between two six-pair SiO2/TiO2 distributed Bragg reflectors. Near infrared transmittance spectra evidence the presence of a stop-band from 1350 to 1850 nm and a cavity resonance centered at 1537 run. Intensity enhancement and narrowing of the I-4(13/2) -> I-4(15/2) emission band of Er3+ ion were observed, owing to the cavity effect. A cavity quality factor of 171 was achieved. All observations show excellent agreement with transfer matrix simulations, leading to improvements of the devices design operating in laser regime. (C) 2008 Elsevier B.V. All rights reserved.
