ELI5: Explain Like I'm 5


Photonics is the technology that uses light to do things like send messages, take pictures, and make things glow. It works by using special objects called "photons" that help light to travel in an organized way. Photons move in very straight lines, which means that light can be sent through things like tubes or wires. Photons are also able to carry lots of information in a short amount of time, which is why it is so important for things like computers to use them! Photons are used to make things like lasers, which are like super-bright beams of light that can be used for many different things.
