Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals. Instead of relying on ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon ...

space, ground, underwater, data center, and indoor networks. With the evolution of the sixth-generation (6G) mobile communication toward a space-air-ground-sea integrated network, massive data-centric ...

A VLC system consisting of a transmitter and a receiver was constructed, and a serializer/deserializer using 8B13B coding was implemented on an FPGA. The data modulated onto the LED light were ...

As a graduate student at the University of California, San Francisco more than a decade ago, Sarah Goodwin witnessed her PhD advisor, biologist Ron Vale, establish a unique science communication ...
