Advanced Photonics Research, EarlyView.This work introduces a humidity‐modulated strategy to regulate the dynamic transition from quasi‐BICs to BICs based on the symmetry‐breaking in geometry and permittivity for the hybrid photonic‐plasmonic asymmetric gratings. It proves that it is a promising approach for dynamic regulating optical properties and applied in fabricating various micro ...

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes
Advanced Photonics Research, EarlyView.Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced. By tuning permittivity tensors to balance loss compensation (Re(ε∥)/Re(ε⊥)=Im(ε∥)/Im(ε⊥))$\left(\right. \text{Re} \left(\right. \left(\epsilon\right)_{\parallel} \left.\right) / \text{Re} \left(\right.

Advanced Photonics Research, EarlyView.A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...

Multispectral Polarization‐Insensitive Graphene/Silicon Guided Mode Resonance Active Metasurfaces
Advanced Photonics Research, EarlyView.CMOS‐compatible graphene/silicon active metasurfaces based on guided‐mode resonance filters are investigated. Simulations reveal a high extinction ratio (>25 dB), a narrow linewidth (≈1.5 nm), and polarization‐insensitive operation. Multispectral mid‐infrared performance is achieved via geometrical scaling.
