“…All the simulations are done by frequency-domain electromagnetic solver of computer simulation technology (CST) microwave studio. Using this, simulations in [2,4] are tested; results obtained by CST are in well agreement with the paper results, which authorises the simulation process. Fabrication of HMIM waveguide can be done by standard film deposition, photolithography and etching processes [5]. )…”

“…Another key parameter is C.F., which designates the part of energy guided by spacer layer. Mathematically it can be written as [4]

Confinement factor = E_{mode} / E_{total}

where E mode in (2) signifies the mode area energy and E total is the total energy of excitation. Most part of energy is confined in spacer layer due to abrupt change of geometry and dielectric layers, as shown in the mode profile, in Fig.…”

Hybrid metal insulator metal plasmonic waveguide has been investigated at 1550 nm wavelength using frequency-domain electromagnetic solver of computer simulation technology microwave studio. This waveguide overcomes the limitations of conventional plasmonic metal insulator metal waveguide and provides good balance between propagation length and confinement. Propagation length up to 2.5 mm and confinement factor more than 80% have been observed. Waveguide bends such as 90°and S-shaped, based on the presented waveguide have been examined; these bends exhibit more than 90% transmission efficiency in a confinement area of 40 × 200 nm 2. The application of these structures in the design of chip scale integrated circuitry is motivated.

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.

Plasmonics has attracted a lot of interest in the past few years because of its unique features, especially for its ability to confine light in extremely small volumes. However, application of plasmonics is restricted by the large propagation loss associated with plasmonic waveguides. On the other hand, dielectric waveguides enjoy low loss, although the mode confinement is relatively weaker. Hybrid plasmonic waveguides (HPWGs), which combine these two guiding mechanisms, allow one to utilize the benefits of both technologies. Over the past few years there have been intense research activities around the world on this new guiding scheme. In this work the operating principle of HPWGs, various HPWG structures proposed by different research groups, and their potentail applications are reviewed.
