The concept of transmitting data through light has been around forever. For my undergrad physics lab class in college, my team used a laser to transmit audio. Another team did a similar thing except they hooked it up to computers and sent jpeg's. This was probably seven years ago, and this wasn't the first time that projects like this had been done for this class.
