Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

Rain observations in tropical storm Cora [PDF]

Passive microwave observations were made in tropical storm Cora at 19.35 and 94GHz. These observations suggest that 94GHz is appropriate for mapping the extent of rain over either land or ocean backgrounds and that some rainfall intensity measurement is ...

3D Microprinting of Structures with Lanthanide‐Based Fluorophores on Optical Fibers for Multiplexed Sensing

Advanced Optical Materials, EarlyView.
Incorporating lanthanide‐based fluorophores into commercial resists for femtosecond direct laser writing enables a novel platform for multiplexed sensing. Porous, periodic, and solid luminescent microstructures fabricated directly on optical fiber tips are presented.

Vat Photopolymerized HEMA/HEA Hydrogels for Solvent‐Responsive Transparency and Optical Encryption

Advanced Optical Materials, EarlyView.
Vat‐photopolymerized HEMA/HEA hydrogels exhibit reversible transparency‐opacity switching via hydration‐induced microphase separation and solvent exchange. The printed materials enable hydration sensing, optical encryption, and information storage, while maintaining high ductility and reversible rheology.

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

Advanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

Advanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Toward an integrated pantropical ocean observing system

Frontiers in Marine Science
Global climate is regulated by the ocean, which stores, releases, and transports large amounts of mass, heat, carbon, and oxygen. Understanding, monitoring, and predicting the exchanges of these quantities across the ocean’s surface, their interactions ...

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

Advanced 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.
