Remember reading an article a while back where they said they did it. Canβt find it but never really explained how it is even possible or how or why someone said look light lets put some data in itl
Using light to communicate has a pretty long history, you just blink lights in a pattern, same as electric signals just without a wire, I mean you can use a βwireβ to make light go further (optical fiber), you send zeros and ones by turning the laser on and off, thatβs all, optical audio connections came to the market in 1983, the undersea internet cable are optical etc, you can blink a flashlight in Morse code and itβs a light based communication, swap flashlight with a laser and you have βan information in a laser beamβ, thatβs all, you want to send more info faster just blink faster
