“…When the temperature varies from −100 °C to 60 °C, the mode 3, mode 2 and the mode 1 shift 40 nm, 58 nm and 210 nm, respectively, resulting in 0.25 nm/°C, 0.3625 nm/°C and 1.3125 nm/°C for the mode 1, mode 2 and mode 3, respectively. To the best of our knowledge, the RI and temperature sensitivity of the proposed plasmonic MIM waveguide is much higher than the previously reported SPPs waveguide sensors and LSPRs sensors [7,12,24,37,48,50,51].…”

An ultra-high plasmonic refractive index sensing structure composed of a metal–insulator–metal (MIM) waveguide coupled to a T-shape cavity and several metal nanorod defects is proposed and investigated by using finite element method. The designed plasmonic MIM waveguide can constitute a cavity resonance zone and the metal nanorod defects can effectively trap the light in the T-shape cavity. The results reveal that both the size of defects in wider rectangular cavity and the length of narrower rectangular cavity are primary factors increasing the sensitivity performance. The sensitivity can achieve as high as 8280 nm/RIU (RIU denotes the refractive index unit), which is the highest sensitivity reported in plasmonic MIM waveguide-based sensors to our knowledge. In addition, the proposed structure can also serve as a temperature sensor with temperature sensitivity as high as 3.30 nm/°C. The designed structure with simplicity and ease of fabrication can be applied in sensitivity nanometer scale refractive index sensor and may potentially be used in optical on-chip nanosensor.

“…The proposed structure is also suitable to be served as a nanoscale temperature sensor [22,37,48] and has the route to compensate temperature for sensor [12,24,49,50,51]. As a temperature sensor, a liquid, ethanol, with high RI temperature coefficient (i.e., d n /d T = 3.94 × 10 −4 ) can be loaded into the slit and T-shape cavity.…”

“…The electrical field originating from charge density oscillations is quite sensitive, evanescently decaying, to the change in the refractive indices of the dielectric materials, particularly in the visible or near-infrared bands [29]. Based on this fundamental, researchers have suggested many various plasmonic structures for diverse sensing employments [1,19,21,28,38]. The trapping of biomolecules under testing in the active plasmonic region of the sensor modifies the refractive index in biomolecular sensing applications and crucially affects the distribution of the excited SPPs.…”

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.

In order to improve the low temperature sensitivity of conventional sensors, a plasmonic multifunction temperature sensor with high sensitivity is proposed and investigated systematically in this paper. The sensor consists of two metal layers and two ethanol-sealed elliptical resonators connected to a straight waveguide by two rectangular tubes. We numerically analyzed the transmission characteristics of the Nano-device to assess its performance with the finite element method and achieved great optical properties. The results show that an obvious blue shift of the transmission spectrum appears by varying temperatures, exhibiting a great sensing effect. Sensitivity of the sensor reaches −3.64 nm/°C, far greater than conventional temperature sensors. Our research also demonstrates that the transmission spectrum could be modulated efficiently by the ratio of semi-short axis to semi-major axis of the ellipse resonators and the width of two same rectangular tubes. Furthermore, the Nano-device has a filtering characteristic. The transmittances of pass-band and stop-band are 96.1% and 0.1%, respectively. The results of this study can pave the way for low-cost sensing application in high-density photonic circuits and biosensors.
