Abstract Among various flat optical devices, metasurfaces have presented their great ability in efficient manipulation of light fields and been proposed for variety devices with specific functionalities. However, due to the high phase dispersion building blocks, significantly suffer from large chromatic aberration. Here we propose a design principle realize achromatic metasurface which successfully eliminate aberration over continuous wavelength region 1200 1680 nm circularly-polarized...
Metalens-array–based quantum source Spontaneous down-conversion is an exotic optical process in a nonlinear crystal which high-energy photon splits into two lower-energy photons that are mechanically entangled. These entangled pairs valuable commodities for information processing and communications. Because the experimental setup usually performed with bulk components, there need to decrease size scale application. Li et al. combined array of specialized metalenses show can be shrunk...
Abstract Metalens, a prominent application of two-dimensional metasurfaces, has demonstrated powerful abilities even beyond traditional optical lenses. By manipulating the phase distribution metalens composed appropriately arranged nanoscale building blocks, wavefront incident wave can be controlled based on Huygens principle, thus achieving desired reflected and transmitted for many different purposes. Metalenses will lead revolution in imaging due to its flat nature compact size,...
Ideal imaging, which is constantly pursued, requires the collection of all kinds optical information objects in view, such as three-dimensional spatial (3D) including planar distribution and depth, colors, i.e., spectral (1D). Although imaging have individually evolved rapidly, their straightforward combination a cumbersome system, severely hindering practical applications four-dimensional (4D) imaging. Here, we demonstrate ultra-compact light-field (SLIM) by using transversely dispersive...
The three primary colour model, i.e., red, green, and blue based on the perception of human eye, has been widely used in imaging. most common approach for obtaining information is to use a Bayer filter, which filters light with four pixels an imaging sensor form effective pixel. However, its energy utilization efficiency collection are limited low level due three-channel filtering nature. Here, by employing inverse-design method, we demonstrate pixel-level metasurface-based Bayer-type router...
