An allocentric human odometer for perceiving distances on the ground plane

open access: yeseLife
We reliably judge locations of static objects when we walk despite the retinal images of these objects moving with every step we take. Here, we showed our brains solve this optical illusion by adopting an allocentric spatial reference frame.

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

open access: yesAdvanced 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

Structural Colors from Ultrathin Lignin Films

open access: yesAdvanced Optical Materials, EarlyView.
Thickness‐dependent structural colors in ultrathin lignin films generate a full visible palette, tuned simply by solution concentration and spin speed. Abstract Structural colors offer a sustainable alternative to toxic pigments and dyes, yet their realization from lignin, the most abundant aromatic biopolymer, has remained elusive.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
