"Color is crucial," as pop artist Roy Lichtenstein famously said, but the significance of color extends far beyond art. From the creation of Prussian blue—the first synthetic pigment—to quantum dots in modern display ...
Researchers at City University of Hong Kong (CityUHK) have made a discovery that significantly reduces energy loss in metal nanostructures. By altering the geometrical dimensions of these structures, researchers have unlocked ...
Researchers at the University of Ottawa have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb ...
A recent study has unveiled a transformative nonlinear optical metasurface technology. This new technology, characterized by structures smaller than the wavelength of light, paves the way for significant advancements in next-generation ...
Augmented reality (AR) takes digital images and superimposes them onto real-world views. But AR is more than a new way to play video games; it could transform surgery and self-driving cars. To make the technology easier to ...
Photonic applications harness the power of light-matter interactions to generate various intriguing phenomena. This has enabled major advances in communications, medicine, and spectroscopy, among others, and is also used ...
As the global energy crisis intensifies and climate change accelerates, finding sustainable solutions for energy management is increasingly urgent. One promising approach is passive radiative cooling, a technology that allows ...
Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never before possible.
The fine and efficient control of the properties of light at ultrafast speed down to the picosecond timescale is a challenging task, crucial for many scientific applications and technologies. For instance, in free-space optical ...
