By leveraging the concept of chirality, or the difference of a shape from its mirror image, EPFL scientists have engineered ...
Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed ...
Shine on: how do materials emit polarized light? Many materials emit light in ways that encode information in its polarization. According to researchers at École Polytechnique Fédérale de Lausanne ...
Wearable visible light communication systems face fundamental limitations in dense multi-input multioutput configurations due to signal crosstalk between channels. Here, we demonstrate shear-aligned ...
In this paper, we present an electrically controllable microoptical component for light beam steering and light intensity distribution built on the combination of nematic liquid crystal (LC) and ...
Crystals made of lithium, cobalt, selenium, and oxygen seem to defy the conventions of symmetry in the way polarized light (arrows) rotates as it passes through the crystal.
This study investigates the polarized radiance of ice clouds in visible and near-infrared bands, with a focus on optimizing ice crystal model parameters. We developed a comprehensive optical property ...
Defying Logic: Symmetrical Crystals Can Interact With Light Asymmetrically You’d think there would be a law against this, and scientists thought there was, but somehow it happens, and it could ...
Most pixels in cameras detect only red, green or blue light. A sensor made from perovskite materials absorbs all three, improving image brightness and resolution.
