Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

Advanced Optical Materials, Volume 14, Issue 3, 19 January 2026.
Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

Stacked Time‐Varying Metasurfaces

Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Stacked, spatially uniform, time‐modulated metasurfaces replace cumbersome in‐plane modulation. A general design framework optimizes independently programmed temporal functions across cylindrical meta‐atom arrays with time‐varying plasma/collision frequencies, yielding magnet‐free isolation at the carrier and a temporal circulator analogue.

Time‐Domain Near‐Field Scanning Microscopy of Terahertz Metasurfaces

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Time‐domain near‐field scanning terahertz microscopy provides direct access to subwavelength electromagnetic fields on metasurfaces. By combining controlled polarization excitation with nanoscale probing, this technique enables quantitative visualization of localized hotspots, surface‐wave propagation, and wavefront manipulation, offering a powerful ...
