Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

Researchers in China published a paper describing a theoretical model for photonic computing that used light particles instead of electrons for faster processing. The team developed “parallel optical ...

The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?

When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially ...

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for ...

International Day of Light, proclaimed by UNESCO, highlights the fundamental role of light-based technologies in advancing science, innovation, and international cooperation. Among these technologies, ...
