- In this work, the author suggested some criteria in order to have glass ceramic materials behaving as an effective optical medium for light propagation. Briefly, small sizes and homogeneous distribution for the nanoparticles are necessary. It is clear that, in order to satisfy these requirements, the choice of the fabrication process becomes a fundamental step. Topdown and bottomup are the two approaches followed in the solgel method for the growth of nanocrystals inside the host amorphous matrix. In the former, starting from a more complex and larger system, thanks to a controllable process such as thermal treatment, lithography or laser irradiation, it is possible to modify the structure of the parent amorphous material in order to create a nanocomposite material. The bottom-up approaches seek to have smaller components and arrange them into a more complex system. A typical example is an amorphous host loaded with previously synthesized nanocrystals. In this paper we present and discuss the most significant results obtained by our research groups on Er3+ -doped SiO2: HfO2 glass ceramic waveguides fabricated by solgel process and dipcoating technique (literal)
