Jumping spiders (Salticidae) rely on accurate depth perception for predation and navigation.
They accomplish depth perception, despite their tiny brains, by using specialized optics …

In recent years, active metasurfaces have emerged as a reconfigurable nanophotonic
platform for the manipulation of light. Here, application of an external stimulus to resonant …

The resolution of conventional optical elements and systems has long been perceived to
satisfy the classic Rayleigh criterion. Paramount efforts have been made to develop different …

Microscopic imaging in three dimensions enables numerous biological and clinical
applications. However, high-resolution optical imaging preserved in a relatively large depth …

We demonstrate optimization of optical metasurfaces over 10^ 5–10^ 6 degrees of freedom
in two and three dimensions, 100–1000+ wavelengths (λ) in diameter, with 100+ parameters …

Three-dimensional (3D) light fields with spatially inhomogeneous polarization and intensity
distributions play an increasingly important role in photonics due to their peculiar optical …

Rigorously designed sub-micrometer structure arrays are widely used in metasurfaces for
light modulation. One of the glaring restrictions is the unavailability of easily accessible …

A metasurface is an artificial nanostructured interface that has subwavelength thickness and
that manipulates light by spatially arranged meta-atoms—fundamental building blocks of the …

In recent years there has been a lot of interest in flat lenses, a category that includes
diffractive lenses and metalenses. These lenses have the potential of reducing the size and …

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