“…Therefore, studying the transmission characteristics of SPPs can provide a new idea for the miniaturization and high-density integration of optoelectronic devices. Among the numerous investigating branches, MIM type surface plasmon optical waveguides are widely used in the design of sub-wavelength photonic devices because of low transmission loss, easy fabrication, and strong electromagnetic field confinement, such as coupler [8], filter [9,10], interferometer [11], sensor [12,13], and beam splitter [14]. Furthermore, researchers have also carried out extensive research on the novel feature of PIT effect, which is a phenomenon based on the interaction of SPPs propagating in different resonators and along different paths.…”

In this paper, the investigation about a metal-insulator-metal (MIM) compound plasmonic waveguide is reported, which possesses the transmission property of plasmon induced transparency (PIT) and exhibits the potential application of refractive index sensing. The waveguide structure consists of an MIM-type bus waveguide, a horizontally placed asymmetric H-type resonator (AHR), and a circular ring resonator (CRR). The AHR is directly coupled with the bus waveguide, while the CRR is directly coupled to the AHR, but is indirectly coupled to the bus waveguide. Due to the destructive interference between two different transmission paths, PIT effect can be observed in the transmission spectrum. The finite element method (FEM) is used to study the PIT effect in detail. The results show that the transmission characteristics can be flexibly adjusted by changing the geometric parameters of the structure, and the proposed waveguide structure has potential application prospects in the area of temperature and refractive index sensing with higher sensitivity, better figure of merit, and in the area of slow light photonic devices.

“…Both in theory and in practice, a wide range of SPP-based devices, including sensors [4], Plasmon-induced transparent (PIT) structures [5,6], Lasers [7], Logic circuits [8] and optical filters [9], were recently suggested and developed. Owing to their exceptional sensitivity towards any changes in refractive indices (RI) of the metal and dielectric stacks, SPP-based sensor concepts attract unprecedented attention for label-free, rapid [10,11] molecular detection of Glucose [12], Drugs [13], Proteins [14], DNA [15] as well as physical parameters such as temperature [16] for biomedical and environmental monitoring devices.…”

In this paper, we designed a metal-insulator-metal (MIM) waveguides based plasmonic sensor coupled with a racetrack cavity adorned with zero Dimensional (0D) nanorod-arrays exhibiting high sensitivity detection of refractive index variations measured as spectral shifts in the resonance wavelengths. The finite-difference time-domain method (FDTD) was used to simulate and study the optical platform based on MIM waveguide and nanorod-array racetrack resonator as a detection refractive index (RI) sensor and for temperature and Diabetes sensing, with sensitivity as high as 4250 nm per RIU and 0.42 nm/°C and 3204 nm/RIU, respectively. The nanorod arrays on the racetrack resonator enhance the light-matter interaction. Which increased the sensitivity. We evaluated the impacts of radius and refractive index on the racetrack resonator's sensitivity using the spectra shifts as sensor performance. As a result, the proposed plasmonic structures exhibit strong potential for a variety of sensor applications for offering high-sensitivity detection of low concentrations of small molecules similar to glucose and temperature.

Investigation and analysis of a tunable plasmonic filter based on the Kerr nonlinear effect of a gold nanocomposite

In this study, an all-optical plasmonic filter is introduced based on metal-insulator-metal waveguides coupled with a square nanocavity filled with a nonlinear Kerr material. This structure is numerically investigated using the finite element method. The structure is then analyzed under linear and nonlinear regimes. The nonlinear material inside the square nanocavity includes gold nanocomposite, and its effective parameters are measured using the Maxwell-Garnett theory. The simulation results show that the resonance peak of the filter structure can be adjusted by changing the physical properties of the gold nanoparticles. Furthermore, we can tune the resonant wavelength within the transmission spectrum by considering the Kerr effect of the gold nanocomposite, and by adjusting the incident light signal without changing the dimensions and physical characteristics of the proposed filter structure. Due to the compact size and the simplicity of fabrication, the proposed plasmonic nanofilter is an ideal option for designing the integrated optical circuits.
