Scientists have found a way to trap light in an extremely thin layer, potentially reshaping how future photonic devices are built.

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This echelon diffraction grating came ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Imagine a pair of augmented reality glasses that can filter out visual “noise,” letting only the light you want reach your eyes, not just by color, but by direction. This kind of precision light ...

i would like to simulate the efficiencies of blazed gratings in an off-plane mount in the 50eV-150eV range. I would like to know whether it is possible to do this with this code and if yes, there is ...

Hello，from these figures, we know that the angle of incidence is set to 80°, the grating line density is 5000000.0l/m, the diffraction order is -1, the photon energy of the light source is 620eV, that ...
