PHOTONICA2019 will include five days of tutorial, keynote and invited lectures, progress reports, contributed talks and poster presentations. It is conceived as a school for educating young scientists and the conference facilitating the exchange of new ideas and knowledge in cutting-edge research in Europe and beyond. It brings together not only the scientists from academic and government research institutions, but also the partners from high-tech industry. This concept proved to be very successful in the last five meetings, with participation around 300 eminent scientists, young researchers, and companies representatives from the field of photonics.
