Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission
Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Optical Poling of Ferroelectric Liquids
Advanced Optical Materials, EarlyView.The optical control of size and shape of polar domains in ferroelectric nematic liquid crystal cells is reported. In sufficiently thin samples, light irradiation induces the formation of a novel singular spiral‐shape arrangement of the polar director as a response to localized illumination.

Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking
Advanced Photonics Research, EarlyView.Giant second‐harmonic generation (SHG) susceptibility, on the order of 1000 pm V−1, in SnSe with ferroelectric stacking is demonstrated by theoretical and experimental methods. SHG microscopy is utilized to study few‐layer ferroelectric SnSe flakes on mica substrates. Stripe‐like features in SHG mapping indicate ferroelectric domains. Strong wavelength‐
