Special Issue Information

Dear Colleagues,

Surface plasmon polariton (SPP) light field modulation based on nanostructures is a core research direction in nanophotonics. By allowing precise design and control of the geometric parameters, material composition, and spatial arrangement of metal nanostructures, it enables customized manipulation of surface plasmon resonance characteristics to achieve the desired optical response. Surface plasmon engineering provides a powerful platform for developing novel optoelectronic devices and functional materials through "bottom-up" synthesis methods or "top-down" nanofabrication techniques.

This Special Issue, titled “Surface Plasmon Engineering in Nanostructures”, seeks to highlight cutting-edge advances and research at the intersection of optical science and nanotechnology. Plasmonics can break through the diffraction limit and manipulate light on the subwavelength scale. By integrating novel plasmonic materials, superstructure optimization design, and expanded applications, precise control over surface plasmon polariton optical fields can be achieved, covering the spectral bands from ultraviolet to visible, near-infrared, and far-infrared. This Special Issue will serve as a platform to drive future research on nano-optical systems.

We invite authors to submit experimental and theoretical studies, as well as review articles, on topics such as novel designs of nanophotonics; metamaterials and metasurfaces; and nanowaveguide devices based on micro- or nano-structured materials, integrated optics, sensors, or photodetection techniques. We look forward to receiving your submissions.

Active control of multi-mode light–matter interactions is crucial for advancing quantum photonic technologies. Although triple-mode plasmon–exciton systems involving two distinct excitonic transitions offer a pathway to multi-level polaritonic states, achieving reversible electrical tuning at room temperature remains challenging. Here, we numerically investigate an electrically tunable triple-mode strong-coupling system comprising a J-aggregate-coated Au@Ag nanorod coupled with monolayer WS2. The simulated spectra show a UPB–LPB energy separation of approximately 239 meV near the zero-detuning condition. A modest gate voltage (2.0 V to 3.8 V) selectively modulates the middle and lower polariton branches over ∼46 meV, while the upper branch remains largely unaffected. This selective control is elucidated via a triple-mode coupled-oscillator model and Hopfield coefficient analysis, linking the polariton response to the excitonic composition. These results establish a framework for electrically reconfigurable multi-level polaritonic devices, offering potential for ultracompact optical modulators, high-sensitivity multiplexed sensors, and programmable quantum photonic circuits.
