Bismuth Nanogratings With Narrow Plasmon Resonances for Dynamic Polarized Color Generation and Colorimetric Sensing

Advanced Optical Materials, EarlyView.
Bismuth nanogratings are fabricated by pulsed laser deposition onto the nanostructured silver and polycarbonate surfaces of DVDs. They display spectrally‐narrow plasmon resonances yielding vivid colors, which are strongly sensitive to the polarization of light, angle of incidence, nature of the underlying surface and of the surrounding medium (air or ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced 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

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
