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) Er
