Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

The challenges of fabricating micromotors and geartrains with comparable size to a human cell. The problems of powering such motors. How metasurfaces allow projected laser output to power these ...
