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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Monolithically Integrated Fourier Injected REsonator (FIRE) for Passive Coherent Laser Combination

open access: yesAdvanced Photonics Research, EarlyView.
Semiconductor diode‐based Fourier Injected REsonator (FIRE). The concept of free space FIRE, formerly known as the self‐Fourier cavity, is demonstrated for the first time on a chip‐scale device. A very high laser array coherence (97.7% fringe visibility), corresponding to single out‐of‐phase supermode operation, is reported.

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.
