Abstract
  • In this paper we present some result on sol-gel derived silica-hafnia systems. In particular we focus on fabrication, morphological and spectroscopic assessment of Er3+-activated planar waveguides and waveguiding glass ceramics. Results concerning silica micro spheres coated by silica-hafnia film are presented as well. Two examples of silica-hafnia-derived waveguiding glass ceramics, prepared by top-down and bottom-up techniques are reported, and the main optical properties are discussed. Finally, some properties of activated microspherical resonators, having a silica core, obtained by melting the end of a telecom fiber, coated with an Er3+-doped 70SiO2-30HfO2 film, are presented.
