We report on the integration of erbium doped silicon-rich oxide into toroidal microcavities. Coupling of erbium ions to microtorus whispering gallery modes is evidenced at room temperature under excitation of silicon clusters. The fabrication process is controlled so that no luminescence quenching occurs during the silica melting step. The spatial and spectral distributions of outgoing light are investigated thanks to independent excitation and collection optics.
