Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...
In a new publication from Opto-Electronic Advances the research group of Professor Xiong Wei, from Huazhong University of Science and Technology, Wuhan, China, discuss recent advances in optical dynamic meta-holography.
Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view.
New frontiers have opened in the world of preventing data breaches by using light of two different wavelengths—visible and infrared light. This is achieved by using a new material called a metasurface that makes extreme ...
Video conferencing played a key role during the COVID-19 pandemic and is set to dominate many meetings in the future. To realize the true feeling of a face-to-face dialog, three dimensional video is required and yet the holographic ...
Terahertz radiation, between infrared and microwave radiation in the electromagnetic spectrum, possesses unique advantages for fundamental studies and practical applications. The ability to generate and manipulate broadband ...
Metasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the more time it takes for light to pass ...
New research by a City College of New York team has uncovered a novel way to combine two different states of matter. For one of the first times, topological photons—light—has been combined with lattice vibrations, also ...
Electrical engineers at Duke University have discovered that changing the physical shape of a class of materials commonly used in electronics and near- and mid-infrared photonics—chalcogenide glasses— can extend their ...
An international team, led by Swinburne University of Technology and Australian National University (ANU), have made a breakthrough discovery that could potentially lead to faster, more accurate molecular or virus tests, ...
