Finite-Size Effect Induced Spatial-Spectral Mode Splitting in Membrane Metasurfaces
Chih-Zong Deng, Mu-Hsin Chen, Chun-Hao Chiang +4
This work reports the spatial-spectral engineering and finite-size quantization of optical modes within a triangular-lattice silicon nitride membrane metasurface. Truncating the la…
Freestanding Resist Metasurface Supporting Higher-Order BICs for Efficient Field Enhancement in TMD Monolayers
Chih-Zong Deng, Sunhao Shi, Chun-Hao Chiang +4
Enhancing light-matter coupling in two-dimensional (2D) semiconductors such as transition metal dichalcogenide monolayers remains a central challenge in nanophotonics due to their…
Large-Area Photonic Membranes Achieving Uniform and Strong Enhancement of Photoluminescence and Second-Harmonic Generation in Monolayer WSe2
Fong-Liang Hsieh, Chih-Zong Deng, Shao-Ku Huang +9
Two dimensional transition metal dichalcogenides exhibit strong excitonic responses, direct bandgaps, and remarkable nonlinear optical properties, making them highly attractive for…
Atomic-Scale Light Coupling Control in Ultrathin Photonic Nanomembranes
Chih-Zong Deng, Chun-Hao Chiang, Sunhao Shih +6
Atomic-layer and two-dimensional (2D) materials have emerged as essential building blocks for next-generation quantum and semiconductor technologies, where atomic-scale control ove…
Near-zero-index waveguide for beam steering
Chih-Zong Deng, Eri Igarashi, Yoshihiro Honda
Zero-index materials (ZIMs) have become popular because of their unique optical behaviors, such as infinite effective wavelengths and spatially uniform electromagnetic distribution…
