k‐Selective Electrical‐to‐Magnon Transduction with Finite‐Element‐Resolved Sub‐Micron Nanoantennas
We introduce a coupled finite‐element‐finite‐difference framework that links impedance‐matched nanoantenna geometries to propagating spin‐wave dynamics, capturing skin effects, proximity effects, and taper leakage beyond uniform‐current models. Applied to coplanar‐waveguide and stripline nanoantennas on yttrium‐iron‐garnet, the simulations achieve ...

Multifunctional Metasurfaces for Bridging Terahertz Waves in Free Space and Waveguides
A multifunctional terahertz metasurface capable of simultaneous orthogonal polarization conversion and phase modulation is integrated onto a dielectric slab waveguide, thereby enabling efficient free‐space‐to‐guided‐wave coupling. By implementing tailored phase gradients on the metasurface, we demonstrate the formation of a focused spot within the ...

Metalens‐Enabled Twisted Chromatic Dispersion
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Halide perovskites in wide‐spectrum photodetection
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.
