Abstract
We investigate the spectral properties of an optically pumped micro-cavity made of a half-wavelength erbium-doped SiO2 layer sandwiched between two six-period SiO2/TiO2 distributed Bragg reflectors. The structure, grown by the rf-sputtering technique, is characterised by its transmittance and photoluminescence (PL) spectra. The pump laser operates at lambda(P) = 514 5 nm under optimized oblique incidence Extended (3 x 3) transfer matrix formalism including sources leads to an analytical description of the spectral and angular properties of the emitted field, for both states of polarization As expected, a pronounced enhancement of the PL emission around the cavity resonance is observed (C) 2009 Elsevier B.V.
