Commercial femtosecond direct laser writing (Nanoscribe GT) is utilized to fabricate electrically switchable PEDOT:PSS nanostructures on ITO‐coated glass substrates, as well as underneath and on top of 3D‐printed structures and demonstrates beam‐switching at 1550 nm. Abstract Microscale three‐dimensional (3D)‐printing, with its remarkable precision and

Planar metasurface retroreflector
Metasurfaces are two-dimensional arrangements of subwavelength scatterers that control the propagation of optical waves. Here, we show that cascaded metasurfaces, each performing a predefined mathematical transformation, provide a new optical design framework that enables new functionalities not yet demonstrated with single metasurfaces.

Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

Controllable Angular Scattering with a Bianisotropic Metasurface [PDF]
We propose the concept of a bianisotropic metasurface with controllable angular scattering. We illustrate this concept with the synthesis and the analysis of a metasurface exhibiting controllable absorption and transmission phase as function of the incidence angle.

Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces
A thin gold layer can selectively enhance the directional radiation of a perovskite quantum dot (QD)1D metasurface by incorporating hybrid plasmonic excitation and redistributing diffraction orders from substrate to cover. The use of template‐assisted self‐assembly techniques enables breakthrough tunability in radiative properties over large areas ...

Summary: The development of coding metasurface opens an important development direction for beam modulator components. However, the lack of dynamic tunability is a major obstacle to the development and practicality of terahertz coding metasurface.

Polar dielectrics with low crystal symmetry and sharp phonon resonances can support hyperbolic shear polaritons - highly confined surface modes with frequency-dependent optical axes and asymmetric dissipation features. So far, these modes have been observed only in bulk natural materials at mid-infrared frequencies, with properties limited by available

A versatile, high‐precision, non‐contaminating sugar‐transferring method is developed for nanofabrication on newly developed ultrathin and flexible diamond films. It enables the flexible all‐diamond metasurfaces, for the first time, come into the public eyes.
