A hybrid plasmonic waveguide consisting of a high-index dielectric ridge sandwiched between double graphene sheets is shown to support hybrid plasmonic modes at far-infrared regime with strong confinement and low damping rates.
A waveguiding configuration consisting of a semiconductor nanowire embedded in a dielectric-coated V-shaped metal groove is presented. The modal properties of the fundamental quasi-TE hybrid plasmonic mode are investigated at the wavelength of 1550 nm. Simulation results reveal that by tuning the size of the nanowire, the hybridization between the dielectric mode, and plasmonic mode could be effectively...
We propose a novel type of dielectric-loaded plasmonic waveguide consisting of a rectangular metal nanrod covered by dielectric layers. Subwavelength mode confinement and moderate propagation distance can be achieved simultaneously.
A novel hybrid plasmonic waveguide based on a triangular metal wedge is proposed. The structure could achieve ultra-deep-subwavelength mode confinement with low-loss, while its mode properties are still quite tolerant to fabrication errors.
A novel dielectric-loaded surface plasmon polariton (DLSPP) waveguide with a nano-hole within the dielectric ridge is proposed. Compared to the conventional DLSPP waveguide, the structure could achieve increased propagation length while maintaining its subwavelength confinement.
