Plasmonic Wave Manipulation in Photonic Applications

Plasmonic wave manipulation harnesses the strong confinement of electromagnetic fields at metal–dielectric interfaces to guide, modulate and enhance light–matter interactions on subwavelength scales. By coupling photons to collective electron oscillations, surface plasmon polaritons (SPPs) and related phonon polaritons achieve field localisation far beyond the diffraction limit, enabling miniaturised photonic components. Recent advances exploit engineered nanostructures—ranging from metasurfaces and nanoantennas to topological insulator films—to tailor phase, amplitude and polarisation of surface waves with high precision. Techniques such as dispersion engineering, geometric-phase modulation and active feedback control permit dynamic reconfiguration of near-field patterns, orbital-angular-momentum states and directional emission. These capabilities underpin a new generation of devices for optical communications, on-chip quantum photonics, biosensing and information processing across a broad spectral range from the visible to the terahertz. The integration of plasmonic elements with complementary materials and real-time control schemes promises ultracompact circuits with enhanced functionality, opening pathways to high-capacity data multiplexing, ultrasensitive detection and adaptive optoelectronic systems.

Research from Nature Portfolio

A study has demonstrated dispersion-driven multiplication of orbital angular momentum in surface phonon polaritons confined to silicon carbide membranes. By exploiting a sublinear dispersion regime, the topological charge of polaritonic vortices can be switched within a narrow frequency window, allowing reconfigurable on-chip vortex multiplexing at mid-infrared wavelengths. This approach leverages near-field imaging and Huygens-principle analysis to quantify dynamic topological orders and heralds new routes to mid-infrared orbital-momentum multiplexers. Another investigation explored coherent control of the plasmonic spin-Hall effect through geometric-phase-matched nano-slots on silver films. By tailoring the superimposed inward and outward plasmon profiles for orthogonal spins, arbitrary spin-dependent surface-wave orbitals were generated, enabling dynamically tunable near-field patterns and spin-selective holographic sequences. This spin-enabled control framework offers versatile near-field scanning modalities, holographic data storage and integrated plasmonic tweezers.
