Special Issue Information

Dear Colleagues,

Plasmonics, a highly topical subsection of Photonics, is recognised as the cutting edge of next-generation photonic technology, being at the boundary of optics, condensed matter physics, nanotechnology and material sciences.

A surface plasmon is a quantum electromagnetic phenomenon arising from the interaction of light with typically free electrons at a metal–dielectric interface. Under certain conditions, the energy carried by the photons is transferred to collective excitations of free electrons, either creating localised surface plasmons (SPs) or propagating surface plasmon polaritons (SPPs) at that interface.

Plasmonics takes advantage of the coupling of light to charges and allows breaking the diffraction limit for the localisation of light into subwavelength dimensions, enabling strong field enhancements.

The development of improved plasmonic systems, including advanced and active control over their physical properties (so called active Plasmonics), will accelerate and transform a sizeable number of industries with a range of disruptive enabling technologies. New plasmonic systems can form the basis to launch new and better products in a wide range of applications, e.g., in the fields of life sciences, ICT, communications systems, solar harvesting and high efficiency systems. This enabling technology will improve areas including imaging, sensing, light emission, harnessing and harvesting of light beyond the current state of the art.

The ultimate goal in this regard is the generation of novel materials which show improved or even unprecedented photonic, but also electronic, thermal and mechanical characteristics compared to conventional materials: Plasmonic Functional Materials.

Such functional materials can be predicted and analysed using sophisticated frequency domain finite element methods (FEM) of finite difference time domain (FDTD) computational methods and can be generated using a combination of bottom–up and top–down nanotechnology techniques. One of the primary directions within this field is to generate new functional structures and materials and to look for new avenues for fabricating such plasmonic nanostructures.

We propose and numerically investigate a multi-parameter integrated sensor based on a selectively filled D-shaped photonic crystal fiber (PCF). The simple structure can be used to comprehensively detect refractive index, magnetic field, temperature, and voltage. According to the surface plasmon resonance and directional coupling effect, the PCF is coated with a gold nano-film to detect the refractive index of the external environment. In addition, magnetic fluid (water-based Fe3O4), toluene, and nematic liquid crystal (NLC E7) are selectively filled into different cladding air holes of the D-shaped PCF to realize the different sensing of the magnetic field, temperature, and voltage. The measurement of refractive index, magnetic field, temperature, and voltage are independent of each other, so these four parameters can be measured simultaneously. The sensing characteristics of the proposed structure are investigated systematically by the finite element method. The results show that the sensitivities of refractive index, magnetic field, temperature, and voltage are 4600 nm/RIU, 1.375 nm/Oe, 15.143 nm/°C, and 0.971 nm/V, respectively. The presented design based on materials selectively filled with D-shaped PCF might enable promising application in multi-parameter optical sensing. Full article

Here we report on both simulations and experimental results on propagation and transmission of Surface Plasmon Polaritons (SPPs) through tunable gaps which were initially motivated by excitation of SPPs on a periodic arrangement of nanowires with mechanically tuneable periodicity. The general ability to vary the two-dimensional lattice constant results in an additional degree of freedom, permitting excitation of SPP’s for any combination of wavelength and angle of incidence within the tuning range of the system. Fabrication of the tunable system includes a transition from a continuously metal coated surface to small metal ribbons which can be separated from each other as a result of mechanical strain applied to the flexible PDMS substrate. This also results in the creation of tuneable gaps between the metal ribbons and variations in the thickness of the metal coatings. In order to explain the propagation of SPPs through such gaps we have employed Finite Difference Time Domain (FDTD) simulations of SPPs through model systems which contain gaps with varying depths and metal fillings.

Controlling the phase distribution of wavefronts using optical metasurfaces has led to interesting optical properties and applications. Here, we explore the control of phase distribution through polar-dielectric metasurfaces composed of doped SiC nanosphere arrays. We investigate the impact of doping concentration on the optical properties of SiC nano-spheres. Our results indicate that increasing the doping of SiC nanoparticles influenced electric dipolar resonances, whereas it did not change the dipolar resonances. Using this concept, we numerically studied the extension of this idea to form metasurface arrays of single, dimer and linear trimers of the doped SiC nano-spheres. Using different doping schemes, we studied the improvement of the reflectivity at frequencies greater than the longitudinal optical phonon frequency. Full article
