Photonics includes the sciences and techniques that generate, emit, detect, collect, transmit, modulate, amplify photon beams, from the terahertz band (min: 200 Gigahertz) to X-rays. Photonic based projects target the development of photonics core technologies as well as the development of whole products and systems based on photonic components. These photonic technologies are applied in multiple areas, among the most important ones are: personalised healthcare, industry 4.0, smart cities, homes, grid and digital infrastructures, secure digital society, environment and sustainability, frontier research equipment, connected mobility, space and defence, smart farming and food production, knowledge transfer and smart learning, etc.
