Yes, laser manipulated to send datas. Is it possible to use light as carrier of data without affecting its speed. The light signal was one of the first methods in history used to send information to remote distances.  Eg: TV remote controller, fiber cables to send datas (in telephone). To put that in perspective, broadband cable supports up to about 30 megabits per second. The twisted-light system transmits more than 85,000 times more data per second.

Their work might be used to build high-speed satellite communication links, short free-space terrestrial links, or potentially be adapted for use in the fiber optic cables that are used by some Internet service providers.

 Russian astronauts on the International Space Station have transferred scientific data using a laser communication channel for the first time, officials say.
