“…In recent years, plasmonics has become a promising research field due to its diverse applications such as subwavelength optics [1,2], solar cell [3], optical waveguide [4] and bio-sensing [5] in visible and infrared region. In addition to their usage as passive components, a tri-layer Ag/dielectric/Ag plasmonic thermal emitter (PTE) introduced by Tsai et al [6] has been demonstrated as an active device to generate radiation in near and mid-infrared region.…”

A plasmonic thermal emitter (PTE) with periodic block pattern as top layer was investigated. It is found that by adjusting the length and orientation of the rectangle metallic islands inside the block, three polarization-dependent peaks can be obtained in the thermal radiation spectra. The individual mode can be extracted according to different polarization by an external polarizer. Thus, a triple -spectral response PTE can be designed by tuning the appropriate dimensions of the block pattern.

“…It is based on the resonant transmission increase due to the constructive interference similarly to the antireflection coatings for lenses. The same concept can be used in the optical range, for the plasmonic waveguides of different cross-sections [11], [61][62][63] and for the silicon and plasmonic waveguides [64] matching. The coupling efficiency can be enhanced in comparison with the end-fire coupling.…”

An efficient and compact coupler -a device that matches a micro-waveguide and a nano-waveguide -is an essential component for practical applications of nanophotonic systems. The number of coupling approaches has been rapidly increasing in the past ten years with the help of plasmonic structures and metamaterials. In this paper we overview recent as well as common solutions for nanocoupling. More specifically we consider the physical principles of operation of the devices based on a tapered waveguide section, a direct coupler, a lens and a scatterer and support them with a number of examples.Nevertheless, the problem is not only to create efficient waveguides that provide subwavelength mode confinement, but also to make an efficient interface between free space or an optical fiber and a subwavelength nanowaveguide, that is to focus light and launch it efficiently into the waveguide. The artistic view of the situation is depicted in Fig. 1. Trying to pour water from a big bowl into a bottle with a narrow bottleneck, one would waste a lot. However, usage of a funnel simplifies the task and increases the efficiency significantly. An optical coupler plays the role of a funnel for light.

“…The output ports are located symmetrically on either side of the resonator with respect to the input port 1 to obtain identical output powers. The widths of the ring, the input waveguide and the output waveguide are all equal to w. A two-layer antireflection (AR) resonator structure is inserted between the input waveguide and the ring structure to diminish the reflection at port 1 [15]. The widths of these two layers are W r and w, respectively.…”

Novel plasmonic power splitters constructed from a rectangular ring resonator with direct-connected input and output waveguides are presented and numerically investigated. An analytical model and systematic approach for obtaining the appropriate design parameters are developed by designing an equivalent lumped circuit model for the transmission lines and applying it to plasmonic waveguides. This approach can dramatically reduce simulation times required for determining the desired locations of the output waveguides. Three examples are shown, the 1 × 3, 1 × 4, and 1 × 5 equal-power splitters, with the design method being easily extended to any number of output ports.
