Photonics: Technology, Applications & Its Economic Impact: -

Abstract

Photonics is the science and technology of generating,controlling, and detecting photons, which are particles of light – by emission,transmission, amplification, detection, and modulation of light. The 21stcentury will be as dependent on photonics as the 20th centurydepended on the electronics. Photonics explores a wider variety of wavelengthsthan the electromagnetic spectrum, from gamma rays to radio, including X-rays,UV and infrared light. The characteristics of the waves and photons can helpexplore the universe, cure diseases, and might even solve crimes.
