Light that twists as it travels and materials whose internal order is knotted like a pretzel are starting to collide in the ...

Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive ...

A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

USC engineers have developed an optical system that routes light autonomously using thermodynamic principles. Rather than relying on switches, light organizes itself much like particles in a gas ...

A team of researchers at the Ming Hsieh Department of Electrical and Computer Engineering has created a new breakthrough in photonics: the design of the first optical device that follows the emerging ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...

In a paper published July 24 in the journal Nature Nanotechnology, a team of Caltech engineers reports building a metasurface patterned with miniscule tunable antennas capable of reflecting an ...
