Nano Photonics corresponds to the utilization of light in Nanoscale ventures. This field is related with some particular leaps forward in utilizing light in new advances, including silicon-based semiconductors, where nanophotonics enhance speed and execution. Nano photonics or Nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. The nanophotonics idea additionally adds to a more broad classification of nanotechnology that is altering how a portion of the most modest undertakings are dealt with by the innovative work (R&D) bureaus of different fields. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often involves metallic components, which can transport and focus light via surface Plasmon polaritons.The term "Nano-optics", just like the term "optics", usually refers to circumstances involving ultraviolet, visible, and near-infrared light.
