A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial ...

Metasurfaces, as open optical systems, are widely regarded as ideal platforms for creating and exploiting topological exceptional points (EPs) due to their outstanding light-field manipulation ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

Proposed device outlines new paths forward for compact ultra-sensitive optical sensors, multi-band switches with high ...
