oa CSIR Science Scope - A bright future in photonics : photonics
Photonics is the science and technology of generating and controlling photons - particles of light. Photonic devices usually operate in the visible and near infrared region of the electromagnetic spectrum, often at frequencies in the order of hundreds of terahertz (1 terahertz = 1 012 Hz). The holy grail of the photonics community is to make the photon the electron of the future, i.e. ""electronics"" based on photonics. The applications of photonics cover many disciplines, with the single aim of harnessing the photon in fields such as optics, materials science, electrical engineering, nanotechnology, physics and chemistry. The 20th century is often called the century of the electron because of the technological breakthroughs enabled by the electron. It is likely that the 21st century will be known as the century of the photon.
