The Nano photon corresponds to the use of light in companies at the nanometre scale. This field is related to some advances in the use of light in new advances, including silicon-based semiconductors, where nanophotonic improve speed and execution. The Nano-photonics or Nano-optics is the study of the behaviour of light in the nanometric scale and the interaction of nanoscale objects with light. In addition, the idea of nanophotonic adds to a broader classification of nanotechnology that is altering the way in which innovative work agencies (R & D) from different fields deal with a part of the more modest companies. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often involves metallic components, which can transport and focus light through surface Plasmon Polaritons.
