Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation

Advanced Photonics Research, EarlyView.
Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

Advanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Strong Coupling‐Induced Topological Edge‐State Laser in 1D High‐Contrast Grating

Advanced Photonics Research, EarlyView.
This study manipulates lattice constants and filling factors in 1D high‐contrast gratings to induce strong and weak coupling, enabling topological and trivial states. Demonstrating topological edge‐state lasers with improved robustness, lower thresholds, and narrower linewidths, the design supports novel topological laser cavity advancements ...

Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

Advanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications.
