Reaching the highest efficiency of spin Hall effect of light in the near-infrared using all-dielectric metasurfaces

Here, Junsuk Rho and co-workers propose and experimentally demonstrate a metasurface supporting a large and efficient spin Hall effect of light in optical wavelength. The spin Hall shifts reaching ten wavelengths with efficiencies over 70% are observed.

Real-time observation of the spin Hall effect of light using metasurface-enabled single-shot weak measurements

The spin Hall effect of light allows precise identification of unknown interface parameters, yet its measurement has previously required multiple steps. Here, the authors introduce a metasurface-enabled, single-shot, real-time measurement method.

Tunable metasurfaces via the humidity responsive swelling of single-step imprinted polyvinyl alcohol nanostructures

PVA is a hydrogel that has attractive swelling properties for use in tunable photonic applications. Here, the authors exploit PVA with nanoimprint lithography to realize multiplexed optical encryption metasurfaces to display, hide, and destroy encrypted information.

Scalable manufacturing of high-index atomic layer–polymer hybrid metasurfaces for metaphotonics in the visible

The authors propose a method for the scalable manufacturing of metalenses using deep-ultraviolet argon fluoride immersion lithography and wafer-scale nanoimprint lithography, opening a route towards their low-cost, high-throughput mass production.
