A hybrid metasurface composed of Ge dielectric pillars and a VO₂ grating is proposed, which enables functional switching between symmetric and asymmetric polarization conversion in transmission. By continuously tuning the conductivity of VO2, the structure achieves multiple dynamic controls of asymmetric transmission, circular dichroism, and ...

The fundamental index–bandgap trade‐off strictly limits materials for short‐wavelength nanophotonics. The van der Waals crystal CdPS3 emerges as a compelling alternative platform challenging this paradigm. Combining an exceptionally high refractive index approaching 3 with a broad mid‐infrared‐to‐ultraviolet transparency window, CdPS3 unlocks new ...

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.

Single‐Photon Emission From TMDCs through Strong Coupling to EQ Plasmon Modes of an Au Metasurface
Compact, deterministic solid‐state single‐photon sources that operate at room temperature and integrate with planar nanophotonics are essential for the development of scalable quantum photonic technologies. This work presents a TMDC monolayer strongly coupled to a gold (Au) metasurface featuring an electric quadrupole mode, enabling high‐purity single ...

Tunable Plasmon‐Enhanced Wide‐Angle Terahertz Perfect Absorption via Lorentz Media
A planar graphene‐Lorentz‐DBR structure realizes wide‐angle terahertz perfect absorption through a composite phase‐amplitude matching mechanism. The Lorentz dielectric provides dispersive phase compensation and controlled loss, whereas graphene supports dissipative coupling, enabling high absorption up to 80° incidence and multichannel spectral ...
