recommendations! Published in 2025 at "IEEE Photonics Technology Letters"

DOI: 10.1109/lpt.2025.3596639

Abstract: A novel D-shaped fiber optic surface plasmon resonance (SPR) refractive index (RI) sensor with a bimetallic superimposed double-layer metal oxide grating structure is proposed. Ag/Au layers are coated with ZnO and Ta2O5 to considerably increase… read more here.

DOI: 10.1364/oe.27.001660

Abstract: The surface plasmons that are excited by the multiple layer grating structures on the gold thin film are studied using the finite-difference time-domain method in this paper. The structure parameters' effects on the coupling enhancement… read more here.

DOI: 10.1364/ol.485042

Abstract: Achieving Goos-Hänchen shift enhancement with high transmittance or reflectance based on the resonance effect is challenging due to the drop in the resonance region. This Letter demonstrates the realization of large transmitted Goos-Hänchen shifts with… read more here.

DOI: 10.7567/1882-0786/aaf21f

Abstract: A novel dual-layer grating coupler was designed for efficient vertical coupling between a single-mode fiber and silicon nanowires, with characteristics of polarization diversity and both wavelength bands of 1.3 and 1.55 μm. Theoretical analysis and… read more here.
