The first step toward ultra-high-speed Wi-Fi: a laser-radio transmitter

Leaping toward the next generation of wireless-based data communications, researchers say they are making progress extracting and sending data using semiconductor lasers that churn out radio signals across multiple frequencies all at the same time. Data could conceivably be transmitted hundreds of time faster than today’s traditional Radio Frequency (RF) wireless, engineers believe.

It’s the “first laser-radio transmitter,” Harvard University proclaims of its invention in an article on its John A. Paulson School of Engineering and Applied Science (SEAS) website.
