TL;DR: A design principle is proposed to realize achromatic metasurface devices which successfully eliminate the chromatic aberration over a continuous wavelength region from 1200 to 1680 nm for circularly-polarized incidences in a reflection scheme.

TL;DR: Both experiments and modeling suggest that this dynamic infrared gating effect mainly arises from distance-dependent electromagnetic coupling between neighboring coated fibers in the textile yarns, which opens a pathway for developing wearable localized thermal management systems that are autonomous and self-powered, as well as expanding the ability to adapt to demanding environments.

TL;DR: The intrinsic inhibition of interfacial reaction by using silica glass rather than multicomponent glasses as the matrix is reported, resulting in color-tunable phosphor-glass composites not only accessible to three-dimensional printing technique, but also highly efficient and stable.

TL;DR: A metalens-based spectral imaging system with an aplanatic GaN metalens, in which large chromatic dispersion is used to access spectral focus tuning and optical zooming in the visible spectrum, and develops a new imaging technique that advances recent informative optical devices.

TL;DR: In this article, an in situ approach is presented to couple the SNC doping and loading processes through self-limiting nanocrystallization of glassy phase, enabling one-step construction of fully transparent Ga2O3 SNC-glass nanocomposites.
