Researchers provide mathematical solutions to study 2D light interaction in photonic crystal lasers
Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...
Space telescope reveals rare ‘Einstein ring’ phenomenon with startling clarity
The Einstein ring, formed as light from a distant galaxy bends to glow around another object in the foreground, could help ...
Physicists Unlock a New Way to Bend Light, Bringing Superlenses and Cloaking Closer to Reality
Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...
Einstein Was Right – Euclid Just Captured Space-Time Warping in a Perfect Cosmic Ring
Euclid, a space telescope on a mission to uncover the secrets of dark matter and dark energy, has already made a stunning discovery: a perfectly formed Einstein ring hidden in a well-known galaxy.
