Light waves (red arrows) passing through a crystal can reveal magnetic domains in certain 2D antiferromagnets. © 2025 RIKEN ...
In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...
Electrons shot through a crystal could be made to diffract like light waves passing through slats in a blind, or sea waves entering a narrow harbor. Electron diffraction was revolutionary not just ...
Researchers have discovered a method to induce chirality in non-chiral materials using terahertz light. This groundbreaking ...
The devices, which have a myriad of uses in photonics, consist of an array of pixels, each of which can individually control the phase or amplitude of light passing through it or reflecting off it.
This change in orientation affects the light's ability to pass through the liquid crystal layer, enabling the display to produce images. An LCD consists of several layers, including two polarizing ...
Even with just one photon passing through per second, the calcite setup demonstrates how light ‘chooses’ a path, revealing the probabilistic essence of quantum mechanics. Using common ...
