Fabrication and spectroscopic properties of glass-based erbium activated micro-nano photonic structures

This paper presents optical and spectroscopic assessment, as well as morphological and structural characterization of nanoscaled photonic structures: (i) rare earth-activated oxide and fluoride glass ceramics planar waveguides; (ii) Er3+-activated micro-nano silica spheres and core-shell-like structures; (iii) rf sputteringfabricated planar microcavities.
