“…In Figure 7 a, the variation of d in the range of 20–70 nm demonstrates that the proposed structure’s sensitivity and FOM simultaneously achieve above 2000.00 nm/RIU and 110.00 RIU −1 in modes 1 and 2, revealing the robustness of manufacturing. These results with high sensitivity and figure of merit in mode 1 and mode 2 cannot be simultaneously obtained in the reported literature (e.g., [ 97 , 98 , 99 , 100 , 101 , 102 ]). The optimal value is d = 30 nm, which can support the plasmon resonance mode to enhance the proposed structure’s sensitivity and FOM.…”

A plasmonic metal-insulator-metal waveguide filter consisting of one rectangular cavity and three silver baffles is numerically investigated using the finite element method and theoretically described by the cavity resonance mode theory. The proposed structure shows a simple shape with a small number of structural parameters that can function as a plasmonic sensor with a filter property, high sensitivity and figure of merit, and wide bandgap. Simulation results demonstrate that a cavity with three silver baffles could significantly affect the resonance condition and remarkably enhance the sensor performance compared to its counterpart without baffles. The calculated sensitivity (S) and figure of merit (FOM) in the first mode can reach 3300.00 nm/RIU and 170.00 RIU−1. Besides, S and FOM values can simultaneously get above 2000.00 nm/RIU and 110.00 RIU−1 in the first and second modes by varying a broad range of the structural parameters, which are not attainable in the reported literature. The proposed structure can realize multiple modes operating in a wide wavelength range, which may have potential applications in the on-chip plasmonic sensor, filter, and other optical integrated circuits.

“…A change in the resonance wavelength of the resonator, where the material under testing is mounted, can identify the change in the refractive index as a result of a change in material, temperature, humidity, pressure, or molecular concentration. Many research papers investigated different MIM plasmonic sensors which are based on the aforementioned principles [3,18,27].…”

In this paper, a high-sensitive plasmonic sensor based on metal-insulator-metal waveguide coupled with the interesting metal nanoracetrack defects in a cross cavity is proposed and investigated. The sensing characteristics of the proposed design are analyzed by the means of finite difference time domain method which is embedded in the commercial simulator R-Soft. The positions of transmission peaks can be easily manipulated by adjusting both the radius and the distance between the centers of the two racetrack defects in the cavity. The achieved results exhibit a linear relationship between the material's refractive indices and theirs corresponding wavelengths of resonance, whereas the obtained maximum linear sensitivity is 3410 nm/RIU which corresponds to a sensing resolution as precise as 2.93 × 10 −6 RIU. The proposed sensor has great impact on different technologies advancement as it can be implemented in high performance nanosensors and bio-sensing devices.

“…Electromagnetic waves coupled to collective oscillations of free electrons in a metal, known as surface plasmon polaritons (SPPs), its regarded as the most promising way to realize highly integrated optical circuits and has attracted great attention in recent years (Dionne et al 2006). Many Metal-Insulator-Metal (MIM) plasmonic devices based on SPPs have been recently introduced, some of them include plasmonic filters (Hocini et al 2020), sensors (Ben salah et al 2019), splitters (Xiang, D. Li 2014), switches (Zhao, W. Lu 2011), etc... Although MIM has more transmission loss, it can be neglected in nanoscale devices (Han, Z. Liu, L. Forsberg 2006). As a fundamental resonant effect, the Fano resonance, which arises from the interference between a localized state and a continuum band , has been widely known in numerous physic systems, such as metamaterials (Huang et al 2012), a metallic nanodisk (Ren et al 2013).…”

In this paper, a design with high sensitivity of a plasmonic biosensor by waveguide system is proposed, based on Metal-Insulator-Metal (MIM) coupled with unique rectangular cavities, this structure numerically simulated using the Finite-Difference Time-Domain method (FDTD) in two Dimensions (2D), and analyzed for the optimal sensor performance, by detecting the resonance wavelength and varying the refractive index (RI). The results show two sharp transmission peaks with high transmittance and asymmetrical line-shaped Fano resonances achieved with high value of sensitivity is 3010nm/RIU, by taking the wavelength resolution reach as high as 3.84×10-6 RIU. Considering the standards of Chip-scale integrated planar photonic sensing, the newly designed of the proposed structure with such high sensitivity provides remarkable properties suitable for biosensors, filter, and provide a new possibility for designing compact and high-performance plasmonic biosensors devices.
