Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

ZnCl2 Post‐Treatment Enables High‐Efficiency Violet CsPbCl3 Quantum Dot LEDs
Schematic illustration of ZnCl2 post‐treatment–induced doping in CsPbCl3 quantum dots (QDs). ABSTRACT Perovskite light‐emitting diodes (LEDs) have achieved external quantum efficiencies (EQEs) above 20% in the red, green, and blue spectral regions, yet their efficiency rapidly declines as the bandgap widens for shorter‐wavelength emission.

Electrically Reconfigurable Nonvolatile Transmissive Metasurface in Visible
An electrically reconfigurable, non‐volatile metasurface operating in the visible spectrum is demonstrated using just 20 nm thick wide‐bandgap phase change material Sb2S3. On integration with a custom ultrathin silicon micro‐heater, the device achieves reversible switching with a 16 nm resonance tuning range at 610 nm, a wavelength largely under ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
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

Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...
