Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest ...

Quantum computers will break encryption one day. But converting data into light particles and beaming them around using thousands of satellites might be one way around this problem. When you purchase ...

As artificial intelligence grows more powerful, so does its appetite for speed and energy. The quest for faster, smarter systems has driven researchers to an unlikely ally—light itself. A new study by ...

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and ...

Imagine working with special cameras that capture light your eyes can’t even see—ultraviolet rays that cause sunburn or infrared heat signatures that reveal hidden writing. Or perhaps using ...
