A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...

Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, ...

Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then the ...

The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy ...

Broadband achromatic wavefront control, a cornerstone of next-generation photonic systems that supports full-color imaging, multi-spectral sensing ...

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 ...
