“…Varying its thickness, waveguide width and height and the width of the gold stripe, the optimal waveguide geometries for various materials were found with the mode propagation lengths approaching several millimeters. [ 174,175 ] Well-defi ned propagation of the long-range DLSPPW mode with confi nement approximately 1 μm and even below was observed at telecom wavelengths (Figures 21 b,c). [ 176,177 ] The propagation length of the mode was about 0.5 mm (affected by the leakage due to a fi nite thickness of the dielectric layer and the fabrication imperfections), while the theoretical estimation for the potential propagation length is about 3 mm.…”

“…Optical Mater. 2015, 3, 1662-1690 www.MaterialsViews.com www.advopticalmat.de proposed [ 174,175 ] ( Figure 21 a): the dielectric ridge both localizes the mode and increases the effective index contrast. In order to obtain the longest propagation length, the key approach here is ensuring the most symmetric fi eld distributions with respect to the metal stripe, corresponding to the minimal confi nement of the plasmonic fi eld in the metal and, therefore, minimizing absorption losses.…”

Surface plasmon polaritons provide a unique opportunity to localize and guide optical signals on deeply subwavelength scales and can be used as a prospective information carrier in highly integrated photonic circuits. Dielectric‐loaded surface plasmon polariton waveguides present a particular interest for applications offering a unique platform for the realization of integrated active functionalities. This includes active control of plasmonic propagation using thermo‐optic, electro‐optic, and all‐optical switching as well as compensation of propagation losses. In this review, the principles and performance of such waveguides are discussed and the current status of the related active plasmonic components which can be integrated in silicon or other nanophotonic circuitries is summarized. A comparison of dielectric‐loaded and other plasmonic waveguides is presented and various material platforms and design pathways are discussed.

“…6(d)-(g)) could potentially offer ultralong propagation distance in conjunction with ultra-high FoM, which may significantly outperform the BTHPWs in our case study, while also being superior to the recently proposed symmetric hybrid metal wedge waveguides [60]. To provide better compatibility with practical fabrication methods and offer easy connection to external electrodes, long-range dielectric-loaded like configurations [61], [62] might be better alternatives than the structures shown in Fig. 6.…”

We propose a hybrid plasmonic waveguide that incorporates a semiconductor-insulator-metal bow-tie configuration within a low-index gap guarded by semiconductor and metallic nanostructures. Ultratight field confinement (A eff ∼ λ 2 /3100 − λ 2 /120) in conjunction with reasonable propagation distance (L ∼ 56-138 μm) can be achieved simultaneously at a telecommunication wavelength. Compared to a conventional hybrid waveguide, the effective mode area and propagation loss of a typical bow-tie hybrid configuration are reduced by 2-89% and 34-62%, respectively, whereas the figure of merit is enhanced by 53-700%, along with increased power ratio inside the gap region for small gap cases. Studies on fabrication tolerance, waveguide crosstalk, and loss compensation reveal its robust property for practical implementations and remarkable feasibility to realize ultracompact passive and active components. Moreover, we also reveal the broadband feature of the waveguide and show that its concept can be applicable to various other metallic configurations as well, which may open up possibilities for the inventions of numerous high-performance plasmon waveguides and components.

“…So far, the DLSPP waveguide has been studied both experimentally [14][15][16] and theoretically, 17 and used for various plasmonic devices, e.g., thermal tunable filters, 18 splitters, 19 and resonators. From the experimental aspect, for example, the propagation losses of the DLSPP waveguides were reduced by doping the dielectric layer with quantum dots or rare earth ions.…”

The propagation properties of dielectric loaded surface plasmon polariton (DLSPP) waveguide structures have been investigated by using the transfer matrix method (TMM), which is simple and has a fast calculation speed. The results obtained from the TMM agree well with those from the finite element method. As a demonstration, we investigate the waveguide properties of DLSPP structures in the terahertz and near-infrared regimes. The TMM is potentially a powerful and effective tool for studying various plasmonic waveguide structures, which may find important applications in integrated photonic devices and sensors.
