A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study shows that quantum ...

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By ...

Scientists have developed an ultra-thin, paper-like LED that emits a warm, sunlike glow, promising to revolutionize how we light up our homes, devices, and workplaces. By engineering a balance of red, ...

Research results from Innsbruck, Schwabmünchen, and Düsseldorf demonstrate how the most widely used green phosphors in ...

Astronomers spotted the largest flare ever released from a supermassive black hole as it snacked on a giant star.

Forward-looking: Columbia University researchers have developed a compact photonics chip capable of producing dozens of laser wavelengths from a single high-power source, a breakthrough that could ...
