In the past centuries, the scale of engineering optics has evolved toward two opposite
directions: one is represented by giant telescopes with apertures larger than tens of meters …

As artificial 2D materials made of subwavelength inclusions, metasurfaces bear exotic
optical and electromagnetic properties not obtainable in naturally occurring materials. Based …

We experimentally demonstrate the focusing of visible light with ultra-thin, planar
metasurfaces made of concentrically perforated, 30-nm-thick gold films. The perforated nano …

Traditional technologies to generate and manipulate the orbital angular momentum (OAM)
suffer from bulky size and do not lend themselves to nanophotonic systems. An ultrathin …

超构表面是一种基于亚波长结构的功能膜层器件, 也称超表面或二维超构材料.
超构表面可在平面化的亚波长结构内产生异常的相位突变, 从而为包括大口径平面成像 …

Achieving an efficient spectral tuning in liquid‐crystal (LC)‐loaded active photonic
metamaterials has so far remained a challenge due to strong surface anchoring of LC …

Relative to conventional phase‐modulation optical elements, metasurfaces (ie, 2D versions
of metamaterials) have shown novel optical phenomena and promising functionalities with …

Miniaturization of optical structures makes it possible to control light at the nanoscale, but on
the other hand it imposes a challenge of accurately handling numerous unit elements in a …

Metasurfaces, two dimensional (2D) metamaterials comprised of subwavelength features,
can be used to tailor the amplitude, phase and polarisation of an incident electromagnetic …

Traditional objective lenses in modern microscopy, based on the refraction of light, are
restricted by the Rayleigh diffraction limit. The existing methods to overcome this limit can be …
