“…From the overall analysis of optical performance of the HMIMPW, at w = 200 nm, s = 25 nm, and h = 200 nm, the propagation length is obtained as 40 μm, which is better than that of the reported work in References with the confinement of light in the spacer region of around 37%. Moreover, the mode area and power density of HMIMPW have been achieved, respectively as, 0.027 and 74 μm −2 , that are quite decent values than that reported in References 5, 13, 14, 24, 25, and correspondingly. Table shows the comparison of the current work with the abovementioned reported works, in terms of the propagation length, mode area, and power density.…”

“…Moreover, due to the presence of the metal, the plasmonic waveguides are usually suffering with large ohmic loss . Conversely, the concept of hybrid plasmonic waveguide (HPW) combines the properties of plasmonic and dielectric waveguides, and it can minimize the issues of both the individual waveguides . Usually, the modes formed in dielectric waveguide are either transverse electric (TE) or transverse magnetic (TM) in nature, whereas that in plasmonic waveguide are of TM nature; hence, the hybrid modes in HPW are of TM nature only .…”

“…The achievement of deep‐subwavelength power confinement and eligible coupling of the HPWs, have potential applications in the design of nanoscale optical and optoelectronics devices. Different types of planar and cylindrical HPW structures, such as hybrid metal‐insulator‐metal (HMIM), hybrid insulator–metal–insulator (HIMI), hybrid dielectric loaded (HDL), metal cap, and hybrid metal–insulator (HMI) have been reported to reduce the propagation losses, and to enhance the light confinement with the minimization of device dimension. However, the fabrication of cylindrical waveguide is quite complicated.…”

The fundamental mode characteristics of hybrid metal‐insulator‐metal plasmonic waveguide (HMIMPW), consists of a high‐index layer sandwiched between two spacer/low‐index and metal layers, has been explored to achieve relatively high power density with smaller effective mode area in low‐index waveguide region at the wavelength of 1550 nm. The HMIMPW has the advantage of low power loss with relatively large propagation distance, of order of several tens of λ. The simulation results have demonstrated that with spacer thickness of 10 nm, significantly higher confinement of optical mode power (> 65%) can be realized in the spacer region of HMIMPW with relatively smaller effective area of 0.0060 μm2 together with the power density > 200 μm−2. This type of analysis and results are very desirable for several specific applications, like optical sensing, nonlinear optics, optical manipulations. Further, the investigations on crosstalk performance between two parallel HMIMPWs have been addressed in order to realize the high integration density over the photonic chip. The decoupling separation of nearly 560 nm has been accomplished with the thicknesses of low‐ and high‐index regions, respectively, of 10 and 50 nm.

A study on plasmonic waveguide based on hybrid IMI (HIMI) has been reported providing long range propagation and sub-wavelength confinement [7]. To further enhance the light confinement and to lessen the propagation losses, a multi-layered hybrid MIM (HMIM) plasmonic waveguide has been reported [8].…”

This is the first report on 3D sinusoidal Bragg grating structure based on hybrid metal insulator metal (HMIM) plasmonic waveguide. The proposed structure has a gradual change in the refractive index rather than an abrupt change providing excellent filtering characteristics. The device is studied at an operating wavelength of 1.55 μm. The results are based on numerical simulations performed using the software CST microwave studio suite. The transmission characteristics show more than 80% transmission in the passband and near zero transmission in the rejection band. The proposed structure reduces the scattering losses and a wide bandgap of 0.387 μm is achieved. The proposed structure has a track length of 3.784 μm for 11 cells, which is very less compared to previous reports allowing large-scale integration of photonic devices. A microcavity is also formed and its resonance is investigated by introducing a defect length of 0.217 μm in the periodic structure. A peak transmission of 50% and a narrow resonance bandwidth of 0.029 μm are achieved at 1.55 μm resonance wavelength. The quality factor which defines the energy stored in the cavity is Q = 53.

Ultrathin WS₂ Polariton Waveguide for Efficient Light Guiding

Light confinement to sub‐wavelength scales is actively studied for nanophotonic applications because it gives rise to intriguing optical properties with enhanced light‐matter interaction. Herein, an ultrathin exciton–polariton waveguide based on a WS2 multilayer is proposed for sub‐wavelength light guiding. A WS2 waveguide supports guided exciton–polariton modes even with a few tens of nanometers of thickness. It is theoretically confirmed that the WS2 waveguide has significantly lower propagation loss than a plasmonic mode, although its thickness may be similar to that of a plasmonic waveguide. By injecting white light into a fabricated WS2 waveguide, light guiding is experimentally demonstrated through a 20 nm thick WS2 waveguide. Notably, this study integrated the WS2 waveguide with a WSe2 monolayer to demonstrate the coupling of monolayer emission to the polariton waveguide. The results suggest that WS2 multilayers provide a novel material platform with potential for nanophotonic applications, including ultrathin optical integrated circuits.
