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

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...

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

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

Metasurface converts Gaussian beams to uniform light via polarization encoding, boosting NMR co-magnetometer sensitivity 23% for compact quantum sensors.

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 ...
