Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...
A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...
Polarized sunglasses work by using special chemicals to block light polarized in one direction, thereby eliminating about 50% of the light. Light can also be ‘circularly’ polarized, such that the axis ...
New research explores silicon nanorods in metasurfaces for polarization holographic encryption, addressing image recovery and optical performance challenges.
The research group proposed and tested a nano-antenna that uses the specific optical resonance of dielectric nanoparticles to form a near field of circularly polarized light. This technique bolsters ...
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device ...
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be ...
Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...
