Photonics is the science of using light to generate energy, detect information, or transmit information. The main purpose of the photonics engineering field is to develop new and innovative products for medicine, telecommunications, manufacturing, and construction.
Fun Facts about Photons. 1  Not only is light made up of photons, but all electromagnetic energy (i.e. microwaves, radio waves, X-rays) is made up of photons. 2  The original concept of the photon was developed by Albert Einstein. However, it was scientist Gilbert N. Lewis who first used the word photon to describe it. The theory that states that light behaves both like a wave and a particle is called the wave-particle duality theory. Photons are always electrically neutral. They have no electrical charge.
