Understanding and Circumventing Failure Mechanisms in Chalcogenide Optical Phase Change Material Ge2Sb2Se4Te

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 ...

Quantum Emitters in Rhombohedral Boron Nitride

Advanced Optical Materials, EarlyView.
Rhombohedral boron nitride (rBN) is an emerging wide‐bandgap van der Waals (vdW) material with strong second‐order nonlinear optical properties. In this work, optically‐addressable spin defects and single‐photon emitters (SPEs) are fabricated deterministically in rBN.

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.
