The research team proposed a method called aberration-converged annular lithography (ACAL) system, as schematic diagram shown in Figure 1. The Gaussian beam is converted into a collimated annular beam ...

(Left) Schematic diagram of the fabrication of a luminescence-controlled metasurface using the nanoimprint lithography process. (Right) Experiment evaluating the performance of the metasurface's ...

Motors and gear trains with micrometer dimensions and powered by light are fabricated using semiconductor lithography and ...

When will the protruding rear camera on smartphones become obsolete? The implementation of a metasurface, which completely disregards the properties of light, promises to reduce the thickness of a ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

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 ...

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