Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Scientists from the Faculty of Physics at the University of Warsaw, in collaboration with research groups from the Łódź University of Technology, the ...

The Inprentus Team has developed proprietary software to predict diffraction efficiency of real, manufactured groove shapes illuminated at designed scattering conditions, order, and energy range. The ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Here’s a great picture from [Jelly & Marshmallows] that shows off the wild effects of melted chocolate poured onto a diffraction grating. A diffraction grating is a kind of optical component whose ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Inprentus Precision Optics, the worldleader in custom mechanically-ruled blazed diffraction gratings, has announced the addition of Metrology Services to its product offerings. Founded in 2012, ...

A research team has fabricated a subwavelength grating from an epitaxial molybdenum diselenide (MoSe2) layer roughly 42 nanometers thick and measured optical confinement consistent with a bound state ...
