All‐Dielectric Photo‐Thermo‐Optical Metasurfaces for Thermal Landscaping at the Nanoscale

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
Precise nanoscale temperature control is critical yet challenging due to the diffusive nature of heat. We introduce an inverse‐design framework for thermo‐optical all‐dielectric metasurfaces based on a temperature‐dependent absorption library of a‐Si nanoresonators.

Electrically Reconfigurable Nonvolatile Transmissive Metasurface in Visible

Advanced Optical Materials, Volume 14, Issue 11, 20 March 2026.
An electrically reconfigurable, non‐volatile metasurface operating in the visible spectrum is demonstrated using just 20 nm thick wide‐bandgap phase change material Sb2S3. On integration with a custom ultrathin silicon micro‐heater, the device achieves reversible switching with a 16 nm resonance tuning range at 610 nm, a wavelength largely under ...

Angularly Stable Terahertz Metasurface With Multi‐Frequency Narrowband Cross‐Polarization Conversion and Broadband Quarter Waveplate Function

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
A compact dual‐functional reflective terahertz (THz) metasurface is experimentally demonstrated. Near‐unity linear‐to‐cross polarization conversion is achieved at four resonance frequencies: 0.65, 0.80, 2.02, and 2.48 THz. Broadband linear‐to‐circular polarization conversion is realized in two bands, 0.86–1.95 THz (77% fractional bandwith, FBW) and 2 ...

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Multifunctional Programmable Transmissive Metasurface with Phase and Amplitude Manipulation Capability

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This work provides a multifunctional programmable transmissive metasurface with phase and amplitude manipulation capability in the sub‐6G band. By applying different coding strategies, the proposed metasurface can realize vortex beam generation, holographic imaging under phase coding mode, and multi‐beam forming in phase‐amplitude joint coding mode ...
