For decades, laser engineers have wrestled with an embarrassing blind spot: the green-through-yellow slice of the visible ...

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold ...

Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can resolve ...

The Harvard School of Engineering and Applied Sciences (SEAS) has developed the first single lens that can focus the entire visible spectrum of light — including white light — in the same spot and in ...

LOS ANGELES, March 09, 2026 (GLOBE NEWSWIRE) -- Researchers have created a new photonic chip technology that guides light nearly as efficiently as optical fiber. By bringing fiber-like performance ...

For the first time ever, researchers at the US Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. Ames Laboratory senior physicist ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
