Abstract Active metasurfaces provide unique advantages for on-demand light manipulation at a subwavelength scale emerging applications of 3D displays, augmented/virtual reality (AR/VR) glasses, holographic projectors and detection ranging (LiDAR). These put stringent requirements on switching speed, cycling duration, controllability over intermediate states, modulation contrast, optical efficiency operation voltages. However, previous demonstrations focus only particular subsets these key performance device implementation, while the other metrics have remained too low any practical use. Here, we demonstrate an active Huygens’ metasurface based in-situ grown conductive polymer with holistic performance, including speed 60 frames per second (fps), duration more than 2000 cycles without noticeable degradation, hysteresis-free contrast 1400%, 28% voltage range within 1 V. Our design meets all foundational display can be readily incorporated into concepts to deliver high-reliability electrical control its response, paving way compact robust electro-optic metadevices.

Abstract Microscale three‐dimensional (3D)‐printing, with its remarkable precision and ability to create complex structures, has transformed a wide range of applications, from micro‐optics photonics endoscopy quantum technologies. In these fields, miniaturization plays crucial role in unlocking new capabilities. However, despite advancements, most 3D‐printed optical structures have remained static, lacking dynamic behavior tunability. this study, novel approach is presented that combines direct laser writing the electrically switchable properties conductive polymer poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS). This integration facilitates creation directly on objects, marking significant step toward adaptive devices. The fabrication tunable demonstrated via using PEDOT:PSS indium tin oxide (ITO)‐coated glass substrates, as well beneath atop static structures. It found electrical conductivity greyscale remains intact after writing. switching speed, durability, gradual tunability material are explored upon complementary metal‐oxide‐semiconductor (CMOS)‐compatible voltages ranging −3 +2 V. future, advancement opens exciting possibilities micro‐optics, such apertures printed onto micro‐optical lenses.

Abstract Mid‐infrared plasmonic resonance enables nanoscale light confinement at mid‐infrared frequencies, leading to various applications ranging from compact infrared lasers biological and chemical sensing. However, upon fabricated, resonators normally have a fixed frequency, which limits their application frequency range hinders the dynamic tuning potential. Here, with flexible PEDOT:PSS ((poly(ethylenedioxythiophene):poly(styrenesulfonate)) conducting polymer as medium, highly tunable reversible resonances are demonstrated via mechanical stretching. Such resonances, based on stretching‐induced grating‐type morphology of thin‐film, can be readily tuned across large ≈7500 1500 cm −1 . In addition, well in recovery process reproducible under 1000 stretching‐recovery cycles. Furthermore, also show sensing ability by enabling surface‐enhanced absorption molecular moieties. The work paves new way for active will promote development devices.

Abstract Dynamically switchable surface plasmons in conducting polymers constitute an emerging route towards intelligent metasurfaces, but polymer have so far suffered from weak resonances with low quality factors ( Q < 1-2). Here, we address this by nonlocal coupling of individual poly(3,4-ethylenedioxythiophene) (PEDOT) nanoantennas through collective lattice (CLR) periodic arrays (with resonance wavelengths around 2.0-4.5 μm). The results show that careful tuning CLR matching conditions enables organic plasmonic up to 12. Angle-dependent extinction spectra connect the enhancement radiative diffractive effects. Furthermore, strength between nanoantenna units and could be modulated via redox reactions, enabling narrow CLRs reversibly switched large modulation depth (between 7% 45% extinction). By improving , study circumvents previous limitations plasmonics shows feasibility for practical applications active metasurfaces nano-optics.

Abstract Improving light absorption is essential for the development of solar thermoelectric generators. Most efficient absorbers require a back mirror (a thick metal film) to reduce reflectivity by promoting interference between incident and reflected light. However, presence continuous film supposes limitation applications, as it behaves like shortcut Seebeck voltage. In this work, mirror‐free selective absorber presented, designed fabrication devices.

As difference mirror, can be patterned prevent quenching Thanks this, replaced transparent thermoelectric, enabling heat‐to‐energy conversion with negligible loss performance.
