orcid googleholar

The research activity of Applied Photonics - Materials & Devices group, led by Dr. Christos Riziotis, is focusing on the photonics technology engineering combining current advances on novel functional materials, photonics platforms and techniques towards the study of optical phenomena as well as the design and implementation of customized and novel devices for a range of challenging applications.

The group has strong links with industry and other international academic partners and research networks in Europe, with a number of research collaborations in different disciplines ranging from defence and industrial applications to quantum computing and biomedical diagnostics. The research group activities are focusing in four complementary but also diverse directions.
