Optical microscope is one of the most widely used imaging tools for its great flexibility,
reliable design, and low cost. Optical microsphere nanoscope (OMN) is invented as a …

Chiral metasurfaces based on asymmetric meta-atoms have achieved artificial circular
dichroism (CD), spin-dependent wavefront control, near-field imaging, and other spin …

Metasurface is an advanced flat optical component that can flexibly manipulate the
electromagnetic wave in an ultrathin dimension. However, electromagnetic coupling among …

Anti-reflection structures (ARS) in micro/nano-scales provide remarkable opportunities for
broadband and omnidirectional anti-reflection performance. In this work, laser-induced …
