BACKGROUND Metasurfaces have opened up a number of remarkable new approaches to
manipulate light. These flat optical elements are constructed from a dense array of strongly …

Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

Metasurfaces have promising potential to revolutionize a variety of photonic and electronic
device technologies. However, metasurfaces that can simultaneously and independently …

The success of semiconductor electronics is built on the creation of compact, low-power
switching elements that offer routing, logic and memory functions. The availability of …

Metasurfaces provide opportunities for wavefront control, flat optics, and subwavelength light
focusing. We developed an imaging-based nanophotonic method for detecting mid-infrared …

Rapidly developing augmented reality, solid-state light detection and ranging (LIDAR), and
holographic display technologies require spatial light modulators (SLMs) with high …

With rapid advances in optoelectronics, electrochromic materials and devices have received
tremendous attentions from both industry and academia for their strong potentials in …

The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it
did not attract much attention due to a lack of magnetic materials required. Rejuvenated by …

Light projection displays play an increasingly important role in our modern life. Core
projection systems including liquid crystal displays and digital micromirror devices can …

Metasurfaces offer the possibility to shape optical wavefronts with an ultracompact, planar
form factor. However, most metasurfaces are static, and their optical functions are fixed after …
