Dewetting of thin films is a phenomenon in which heat or laser irradiation destabilizes a continuous film, causing it to ...

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing ...

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...

Scientists have demonstrated a new optical computing material made of photon-avalanching nanoparticles. The nanoparticles exhibit a phenomenon called “intrinsic optical bistability,” which enables ...

Metasurfaces are ultra-thin assemblies of subwavelength structures engineered to manipulate light at the nanoscale. When designed from materials with strong optical nonlinearity, these planar ...

Quantitative phase imaging (QPI) is a microscopy technique widely used to investigate cells and tissues. Even though first biomedical applications based on QPI have been developed, both acquisition ...

A hiker captured a rare double optical phenomenon at Casa de Pedra Cave in Brazil on October 17 — a solar halo and a ...

Controlling the spin degree of freedom of light at the microscale is crucial for advancing photonic information processing. Spin-polarized light propagation, combined ...

Since man first looked up to the sky, the moon has been one of the most fascinating and admired celestial bodies. It appears on dark nights, shining with its silvery light, and its shape changes.

Across the world, there are naturally occurring optical illusions that captivate spectators. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt ...

Optical illusions occur naturally in different habitats and conditions across the world. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt flats ...
