Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that enables stable data transmission even under strong ambient light. By ...

Li-Fi is a wireless data system remarkably similar to Wi-Fi, but uses light to send information. Data rates can hit a gigabit a second, while maintaining line-of-sight privacy. pureLiFi is showing off ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a single photon can carry. This leap could make quantum communication more ...

Light communication systems (VIDEO) Optica Caption In the prototype system, the researchers combined mobile green light communication with blue laser underwater communication, deep ultraviolet light ...
