Metallic nanostructures are exceptionally effective at concentrating light into tiny volumes, while dielectric nanostructures excel at storing light with minimal energy loss. Combining these complementary properties has traditionally ...
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
Augmented reality (AR) glasses, lenses thinner than a human hair, and holograms floating above your fingertips may sound like technologies from science fiction. At the heart of these emerging technologies, however, lies a ...
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...
Researchers from Graz University of Technology (TU Graz), Harvard and the University of Texas at Austin (UT Austin) have developed an innovative method for coupling light non-linearly. This opens up new possibilities for ...
A research team at City University of Hong Kong (CityUHK) has developed a new optical corner-detection imaging method that uses azimuthal Hilbert transform metasurfaces and is designed to work as a universal framework. The ...
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular ...
Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light ...
Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered ...
Researchers have developed a chip-based metasurface biosensor that can detect traumatic brain injury (TBI) biomarkers at extremely low levels. With further development, the technology could one day help doctors make a faster ...
