Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Traditional metasurfaces suffer from the drawbacks of pure microwave absorption and low IR emissivity stealth, namely failing to match complex ambient backgrounds with varying IR emissivity and generating excess heat accumulation (enhanced IR thermal radiation).

Continuously tunable narrow-linewidth fiber lasers
Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber ...

Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices
Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.

Engineering Angular Dispersion via Hybrid Local–Nonlocal Metasurfaces
A single‐layer hybrid local–nonlocal silicon metasurface is experimentally demonstrated as a polarization‐insensitive angular filter in transmission. By combining local nanopillar response, lattice‐mediated interactions near the Rayleigh anomaly, and diffraction‐assisted substrate coupling, the platform maintains high transmission within a ±15° $\pm ...
