We report on recent advances in optical nanocomposites materials, planar microcavity, and spherical nano-microspheres. Bottom-up fabrication and optical assessment of Er3+-activated SiO2-HfO2 waveguide glass ceramic, with losses around 0.3 dB/cm at 1.5 ?m is presented. Concerning confined structures, fabrication by rf sputtering technique of an Er3+-activated microcavity with a quality factor of 171 using oxide-based dielectric materials is demonstrated. Fabrication and spectroscopic assessment of sol-gel-derived Er3+-activated silica nano-microspheres with a quantum efficiency of 76% is reported.
