Metamaterials that mimic the order in matters have opened an exciting gateway to reach unprecedented physical properties and functionality unattainable from naturally existing materials. The "atoms" ...

In conclusion, a novel ultra-broadband tunable terahertz absorber of graphene and hierarchically structured plasmonic metamaterials is proposed and studied, and a near-perfect ultra-broadband ...

The creation of photonic materials, circuitry, devices and probes that act on the nanoscale is yielding new opportunities for controlling light in the sub-wavelength regime. The result could be ...

Just as nanoplasmonics reveals the fascinating interplay between light and metal nanoparticles, nanophotonics ventures into the broader realm of light manipulation at the nanometer scale. It explores ...

The conversion of CO2 into e-fuels by light offers a sustainable solution to close the carbon cycle. Researchers at the Laboratory for Nanometallurgy have pioneered an innovative approach to ...

Researchers created a new plasmonic metasurface that sandwiches fluorescent dye molecules between a gold film and 100-nanometer-wide silver cubes. When light hits this structure, it excites ...

The Computational Nano Materials Group headed by Viktor Podolskiy uses mainly computational techniques to investigate light-matter interactions, with emphasis on electromagnetism of nanostructured ...

Optics and photonics are central to many aspects of our lives. Refraction, emission and absorption of light within materials govern imaging, sensing, lighting and communications. However, many of ...
