High‐Efficiency Generation of Vectorial Terahertz Beams via Surface‐Wave‐Excited Dielectric Metasurfaces

Small, EarlyView.
ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

High/low temperature setups for submillimetric samples under various extreme conditions at the AILES beamline

Journal of Synchrotron Radiation, EarlyView.
Two complementary high‐ and low‐temperature experimental setups have been developed at the AILES beamline of Synchrotron SOLEIL to enable infrared and terahertz spectroscopy of submillimetric samples under extreme and well controlled pressure and temperature conditions (from 10 K to 600 K and from vacuum up to 100 GPa).
