Special Issue Information

Dear Colleagues,

According to the bases of optic, photonic-crystal and micro-structured fibers, this Special Issue specifies their metal–dielectric hybrid schemes of steering fiber-guided waves along metal-thin films, metal wires, and periodic metal structures. The excitation of metal surface plasmonic (SP) waves with fiber-waveguide modes has been developed and denoted as one technique of integrated optics. Plasmonic fibers successfully realize near-field probes without a diffraction limit, planar meta-lenses at fiber facets, surface-enhanced Raman scattering spectroscopy, surface-plasmonic-resonance (SPR)-based refractive index sensing, fiber-coupled plasmonic circuits on chips, plasmonic fiber-grating immunosensors, and plasmonic fiber-optic absorbance biosensors. Solid- and hollow-core fiber structures, presented with D-shaped, U-bent-shaped, and tapered schemes, can combine fiber waveguide modes and thin metal films to efficiently generate SP waves. Subwavelength-scaled dielectric wires are also waveguide media considered for the assembly or bundling of thin metal films for plasmonic fibers. This Special Issue invites researchers, who are working on fiber-based SP waves, SPR waves, and the corresponding complex wave guidance, to further present their studies or technical reviews involving sensing–imaging applications, numeric calculations of designs, and modulation methods.

The influence of the conductivity and radius of metal wires embedded into the dielectric fiber on the velocity and attenuation length of terahertz surface plasmon polaritons has been theoretically investigated. It was shown that the phase velocities and attenuation lengths increase with increasing conductivity and radius of the wire. With increasing frequency, the velocity of surface plasmon waves increases and the propagation length decreases. The effect of the dielectric coating on the propagation velocity of surface electromagnetic waves is analyzed. It is shown that the coating leads to a decrease in the phase velocity and an increase in the propagation length of surface plasmon waves. Full article
