A new approach to manufacturing multicolor lenses could inspire a new generation of tiny, cheap, and powerful optics for portable devices such as phones and drones.
The iridescent blue of butterfly wings has inspired researchers to find a solution to a challenge previously considered insurmountable—dynamically tuning advanced optical processes at visible wavelengths.
New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smart devices, communication, gaming and entertainment.
Holography—the science of recording and reconstructing light fields—has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical setups and interference experiments, ...
Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum technologies. One of the ...
Researchers at the UCLA Samueli School of Engineering, in collaboration with the Optical Systems Division at Broadcom Inc., report a broadband, polarization-insensitive unidirectional imager that operates in the visible spectrum, ...
In nanophotonics, tiny structures are used to control light at the nanoscale and render it useful for technological applications. A key element here is optical resonators, which trap and amplify light of a certain color (wavelength).
Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions bend. Now, UCLA researchers ...
In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature.
A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair.
