Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy

open access: yesAdvanced Optical Materials, EarlyView.
This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual

Nanoimprinting of Mesoporous Titania: Direct Patterning and Refractive Index Control in the Visible

open access: yesAdvanced Optical Materials, EarlyView.
Nanoimprinted mesoporous TiO₂ (pTiO₂) films are demonstrated as high‐resolution optical materials with tunable porosity, refractive index, and mechanical response. Sub‐micron patterning of planar optics is shown alongside a refractive index contrast Δn ≈0.7.

Non‐Reciprocal Terahertz Topological Sensor on a Silicon Chip

open access: yesAdvanced Optical Materials, EarlyView.
A non‐reciprocal terahertz topological sensor (NTTS) is experimentally demonstrated on a silicon valley photonic crystal chip by detecting the thickness and position changes of a polyimide membrane. The sensor exploits detuning between clockwise and counterclockwise topological cavity modes, induced by integrated magneto‐optical InSb, to achieve non ...

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

Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

open access: yesAdvanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.
