“…In recent years, MIM waveguides have received widespread attention due to their simple structure, small size and easy integration. [6][7][8] As time went by, various functional photonic devices such as filters, [9] sensors, [10,11] optical switches, [12] slow light devices [13] and splitters [14] designed based on MIM waveguide structures have made great breakthrough in theoretical research and experiments.…”

A plasmonic resonator system consisting of a metal-insulator-metal waveguide and a Q-shaped resonant cavity is proposed in this paper. The transmission properties of surface plasmon polaritons in this structure are investigated using the finite difference in time domain (FDTD) method, and the simulation results contain two resonant dips. And the physical mechanism is studied by the multimode interference coupled mode theory (MICMT), the theoretical results are in highly consistent with the simulation results. Furthermore, the parameters of the Q-shaped cavity can be controlled to adjust two dips respectively. The refractive index sensor with a sensitivity of 1578nm/RIU and figure of merit (FOM) of 175, performs better than most of the similar structures. Therefore, the results of the study are instructive for the design and application of high sensitivity nanoscale refractive index sensors.

“…Nowadays, many waveguide coupling structures based on SPPs have been designed to fabricate various photonic devices, including metal−insulator−metal (MIM) waveguides [16], insulator−metal−insulator waveguides [17], channel waveguides [18,19], and nanoparticle chain waveguides [20]. Among them, MIM waveguides are widely considered and reported by scholars and the media at home and abroad because of their sub-wavelength size, simple structure, easy integration, and high reliability [16,21]. Yang et al [22] designed a coupling structure with a double-gap ring cavity and MIM waveguides with two triangular baffles with a sensitivity of 1500 nm/RIU and figure of merit (FOM) of 65.2.…”

A MIM Waveguide Structure of a High-Performance Refractive Index and Temperature Sensor Based on Fano Resonance

A plasmonic refractive index nanosensor structure consisting of a metal-insulator-metal (MIM) waveguide with two symmetrical rectangle baffles coupled with a connected-concentric-double rings resonator (CCDRR) is presented. In this study, its transmission characteristics were investigated using the finite element method (FEM). The consequences, studied via simulation, revealed that the transmission spectrum of the system presents a sharp asymmetric Fano profile due to the destructive interference between the wide-band mode of two rectangle baffles on the bus waveguide and the narrow-band mode of the CCDRR. The effects of the geometric parameters of the structure on the transmission characteristics were investigated comprehensively. A sensitivity of 2260 nm/RIU and figure of merit (FOM) of 56.5 were the best levels of performance that the designed structure could achieve. In addition, the system could act as a sensor for use for temperature sensing, with a sensitivity that could reach 1.48 nm/°C. The designed structure advances with technology with new detection positions and has good application prospects in other high-sensitivity nanosensor fields, for example, acting as a biosensor to detect the hemoglobin level in the blood.
