A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many ...
The research group led by Professor Yijun Feng and Professor Ke Chen from Nanjing University reports a hybrid-phase strategy ...
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 ...
Broadband achromatic wavefront control, a cornerstone of next-generation photonic systems that supports full-color imaging, multi-spectral sensing ...
