In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...

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 ...

Figure.1 | Tailoring VCSEL performance through cavity geometry engineering. (a) Five distinct cavity geometries—circular, square, D-shaped, mushroom, and pentagonal—enable control over the output ...
