Dual‐Wavelength Switchable Focusing via a Fabry‐Pérot Resonance‐Enabled Hydrogel Metalens
A hydrogel metalens is demonstrated for dual‐wavelength switchable focusing based on Fabry‐Pérot resonance. Under the low relative humidity, the metalens exclusively focuses light with a resonance wavelength of 470 nm and directly reflects light of other wavelengths.

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 ...

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.
