I may be going out on a limb but something tells me we are far off from like transmitting a whole book and storing it in light or beam?
There's no storage in light.
Think about when you talk. The sound comes out, shoots through the air, goes in someone's ear, and then they interpret and remember what you said.
The light is your voice. It is transmitting data, but if there's nobody around to hear it, the data is lost.
The light has to hit a receiver, which translates it into usable data and then saves it to a storage device.
mm I like this, you made it sound so simple!
Thanks! I'm a simple person who is interested in complex things, so I think I've gotten pretty good at these kinds of analogies.
