High‐Numerical‐Aperture, 3D‐Printed All‐Dielectric Harmonic Diffraction Metalens in the Sub‐THz Frequency Range

Advanced Photonics Research, EarlyView.
Herein, a compact all‐dielectric metalens operating at dual sub‐THz frequencies is presented, addressing key challenges in terahertz device miniaturization. Utilizing commercial 3D printing, the metalens achieves high numerical aperture and broadband functionality.

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.

Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication

Advanced Photonics Research, EarlyView.
The on‐chip topological Berry antenna for 6G to Xth‐generation wireless communication is designed via integrating various Berry curvatures for an enhanced antenna aperture and radiation gain. This THz antenna has demonstrated a maximum gain of 17 dBi and chip‐to‐chip wireless communications at 20 Gbps over a distance of 15 cm.
