We aim at constituting a platform for exploiting complementary competences in material science, physics of condensed matter, nanotechnology and photonics for the design, investigation, fabrication and assessment of transparent glass-ceramics based photonic devices finding application in ICT, environment, space, sensing and health. The tailored materials and devices are intended to boost both basic and applied research through innovation in synthesis, measurements, modelling and applications. The network will be a powerful instrument to associate industrial and academic scientists with fundamental and applied science expertise, from complementary disciplines such as physics, chemistry and engineering, interconnecting all of them focusing on the glass-ceramics exploitation chain from the material synthesis to the device fabrication at TRL 4. We plan to establish an original and flexible system to nucleate new concepts and new technologies in glass photonics on the basis of the already consolidated European competences. We have in mind a platform to promote specific networking for an application at the ITN call. The interdisciplinary competences present in this network certainly allow to be exploited in European outreach project to promote transparent glass-ceramics based technologies. The tackled subjects in the framework of this network will have to enhance the growth of technological and scientific competences in the area of glass-ceramics as well as the capability of transferring innovation to the market. We are confident that during the first months of activity, the network will be able to identify breakthrough demands (topics) attracting new productive and excellent scientific stakeholders. The competence sphere of the network activity concerns glassy nanocomposites derived fibres, waveguides, microresonators, microcavities and photonic crystal opals. These structures, when doped by, e.g., metallic nano-objects or nanocrystals activated by rare-earth ions, are very effective for the development of different photonic and optronic devices with specific functionalities covering a broad range, from civil infrastructure, security and environmental protection sensors to solar energy exploitation, from quantum optics devices, to light sources for health care, lighting and manufacturing. We expect solid and reliable foreground and sideground outcomes. We strongly believe that this platform has a solid background and a clear vision of the way to combine advancement of knowledge and technological transfer, with the capability of attracting other partners and of allowing direct application of H2020 goals.
