Photonics - definition
Photonics is an interdisciplinary field of science and technology dealing with the generation, control, transmission and detection of light, in particular electromagnetic radiation in the range from infrared through visible light to ultraviolet. A key aspect of photonics is the use of photons - quanta of light - as carriers of information, energy or measurement signals, which distinguishes it from electronics, where this role is performed by electrons.
Photonics combines knowledge from classical optics, quantum physics, electronics, materials engineering and computer science. Its foundations are phenomena such as refraction, reflection, diffraction, interference, polarisation and the photoelectric effect, but also non-linear processes and quantum interactions of light with matter. Structures and devices capable of controlling light with high precision - such as lasers, optical fibres, photodetectors, optical modulators, diffraction gratings or nonlinear crystals - play a special role here.
The applications of photonics cover a very wide range of technologies. In fibre optic telecommunications, it forms the basis of the infrastructure for fast and reliable data transmission over long distances. In medicine, it enables imaging and diagnostics (e.g. optical tomography, spectroscopy), in industry - precision cutting and material processing, and in life sciences - molecular analysis and structural studies. In computer science, photonics is being developed in the context of optical computing and data transmission technology with very high bandwidth.
In modern technologies such as optical sensors, lidar, quantum communication or photovoltaics, photonics plays a key role in the development of efficient, energy-efficient and scalable solutions. The development of photonics is also supported by advanced materials such as Semiconductors Group III-V, integrated photonics materials and nanostructures that enable the manipulation of light at the submicron level.
