Special Issue Information

Dear Colleagues,

Plasmonics, exploiting the unique optical properties of surface plasmons, has evolved from fundamental studies of light-matter interactions into a platform for advanced photonic applications. It holds great potential to address size mismatch between diffraction-limited photonic devices and nanoscale electronic components. By enabling the manipulation of light at nanoscale, beyond the diffraction limit, plasmonics is paving the way for next-generation photonic applications, including sensing, imaging, ultrafast lasing, optical and quantum communications, and energy conversion. Novel hybrid architectures that merge plasmonics with photonics are now driving the development of highly integrated photonic devices that promise unprecedented performance and miniaturization. 

We are pleased to invite you to submit your original research to the special issue on Plasmonics for Advanced Photonic Applications. This Special Issue aims to highlight recent progress and emerging directions in this rapidly evolving field. The collected contributions encompass both fundamental research, ranging from plasmonic theory and material design to nanoscale field manipulation, and practical photonic applications. This issue seeks to emphasize the role of plasmonics in shaping the future of photonic science and technology. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Plasmon-assisted nonlinear and ultrafast processes
  • Integrated photonics
  • Plasmonic nanolasers and nanocavities
  • Plasmonic biosensors and biomedical applications
  • Topological and chiral plasmonics
  • Quantum photonics
  • Plasmonic effects in energy harvesting and photocatalysis
  • Integration of plasmonics with emerging photonic technologies
  • Computational and theoretical advances
  • 2D material-based plasmonics for tunable photonic systems 

We look forward to receiving your contributions.

This work presents a compact broadband in-fiber polarization filter using gold-deposited square-lattice photonic crystal fiber (PCF) numerically. The finite element method (FEM) is utilized to analyze the transmission characteristics of this PCF. The simulation results indicate that when the cladding hole diameter is 1.5 μm, the large hole diameter is 2.1 μm, the long axis of elliptical holes is 1.96 μm, the short axis of elliptical holes is 0.98 μm, the pitch is 2 μm, and the gold layer thickness is 50 nm, the x-polarized mode can interact with two plasmonic modes, and two surface plasmon resonance (SPR) processes at two common communication windows can be achieved. The length of this PCF filter is set as 0.5 mm, exhibiting the maximum extinction ratio (ER) of −51.4 dB at 1.31 μm and −47.3 dB at 1.55 μm, and the operating bandwidth of >860 nm. Additionally, the estimated splice losses are ~2.22 dB at 1.31 μm and ~1.42 dB at 1.55 μm. It is expected that this small-size PCF-SPR filter, characterized by its efficient filtering performance and wide bandwidth, will serve as a promising candidate for building integrated networks that combine optical fiber communication, sensing, and computing capabilities.

Semiconductor quantum dots (QDs) are attractive materials for light-emitting devices, and the photoluminescence (PL) from QDs can be enhanced near a metal surface due to surface plasmon (SP) resonance. To integrate QDs into metal structures, QD/poly(methyl methacrylate) (PMMA) composite thin films are generally used. However, it has been reported that QDs tend to aggregate in the PMMA matrix. In this study, we fabricated two types of QD/polymer composite thin films with different degrees of QD aggregation by additionally using poly(methyl methacrylate-co-methacrylic acid) (PMMA-co-MA), which is known to prevent QD aggregation. Furthermore, these two types of films were fabricated on Ag films, with the distance between the Ag films and the QDs controlled by Al2O3 spacer layers, and the PL enhancement was compared between the two film types. Finally, we reveal that QD aggregation in the polymer matrix significantly affects the PL enhancement. Although the aggregation trends differed between PMMA and PMMA-co-MA, the results suggest a possible increase in the internal quantum efficiency (IQE) in both film types. Full article
