Self‐Detecting Mid‐Infrared Dual‐Comb Spectroscopy Based on High‐Speed Injection‐Locked Quantum Cascade Lasers

Advanced Photonics Research, EarlyView.
A compact self‐detecting dual‐comb spectroscopy (DCS) system based on dispersion‐engineered, high‐speed packaged quantum cascade lasers (QCLs) at λ≈4.6 μm under coherent injection locking is demonstrated. Broad multiheterodyne comb signal with reduced tooth linewidths by orders of magnitude is recorded.

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.

Switchable Terahertz Beam Steering with Near‐Perfect Ordinary Transmission

Advanced Photonics Research, EarlyView.
This study introduces a reconfigurable metasurface that enables switchable terahertz beam steering upon actuation by a global temperature change. At room temperature, it achieves a true “OFF” state with nearly 100% transmission, behaving as if the metasurface is not present, thereby not distorting incoming light.

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.
