“…Zhou et al [12] have designed an end reflection optical fiber SPR sensor, where one end of the fiber has been coated by silver film and graphene. In [20], SPR sensor based on photonic crystal fiber coated with a graphene layer was designed and numerically analyzed. A D-shape plastic optical fiber SPR sensor based on graphene/gold film has been investigated in [21].…”

A few-mode optical fiber surface plasmon resonance sensor with graphene layer is investigated, firstly, with the aim of studying the behavior of the guided modes and, secondly, with the aim of determining the range of the measured refractive index for some selected few-mode fibers. The results show that as the number of modes propagated in the fiber increases, the maximum sensitivity of a particular mode decreases while the range of the measured refractive index of that mode increases. Also, it is shown that the range can be easily tuned with sensitivity consideration by only adjusting the operating wavelength without any modification of the sensor, which is desirable from practical point of view. In addition, it is shown that the core diameter of the fiber should be chosen according to sensitivity and range needing, where a compromise between them must be found. The study presented in this paper can significantly help in developing new sensing techniques, such as multi-parameter sensing, by monitoring the various responses of the modes. Also, it can be used to customize the sensor for specific sensing applications in various fields, especially to measure refractive indices in subranges of 1.38 to 1.46.

“…grating [1,2], long period grating (LPG) [3,4], dispersion compensation fiber [5] and photonic crystal fiber (PCF) [6]. In addition, Surface plasmon resonance (SPR) technology is introduced into the sensor design [7][8][9], which mainly use the phase matching between evanescent wave and surface plasmon wave to increase sensitivity. In addition, some articles have reported that V-shaped and D-shaped fiber sensors are beneficial to improve sensitivity by breaking the symmetry structure [10][11][12].…”

The sensing characteristics of twin-core fiber for refractive index detection are presented and experimentally investigated. In this work, for the first time, we demonstrate the manufacturing method of optical fiber sensor based on Mach Zehnder interference and surface plasmon resonance. Mode interference and resonance coupling effect are thoroughly realized with the misalignment fusion and silver mirror reaction. It is found that the sensitivity of the proposed sensor is 3020 nm/RIU in the refractive index ranging from 1.3333 to 1.3804, which is much higher than that of the conventional fiber sensor. Moreover, experimental data indicate that this sensor has the advantages of easy fabrication, good repeatability and good stability. According to these characteristics, we introduce one specific application of pregnancy detection to validate the application of the designed sensor in biomedical field.

“…Conventional prism-based SPR coupling configurations were Otto and Kretschmann [3,4]. These prism-based SPR coupling configurations, which are composed of various mechanical and optical elements, have disadvantages of bulkiness, unreliability of mechanical structure, high cost, unsuitability for distributed sensing and mass production [5]. The PCF-based SPR sensor has the advantages of miniaturization, flexible design, lightweight, easy integration and real-time monitoring, and is suitable for medical diagnostics and environmental monitoring [6].…”

In this paper, a dual-core microchannel-based fiber sensor is studied by using finite element method in the visible and near-infrared bands. Plasmonic material gold (Au) is deposited in microchannel to generate the surface plasmon resonance (SPR) effect, so that sensor can detect the change in RI of its surrounding analyte. Simulation results show that the maximum wavelength sensitivity and resolution are 33600nm/RIU and 2.97×10 -6 RIU for y polarization in the RI range of 1.33 to 1.44, respectively. The highest figure of merit (FOM) of the sensor is 961 for y polarization. In addition, we study the effects brought by the structural changes of the fiber sensor, and the results show that the design of "microchannel coating" dramatically improves the refractive index detection ability of the sensor. The D-shaped dual-core microchannel-based photonic crystal fiber sensor proposed in this paper has a simple structure, low manufacturing complexity, and high sensitivity. Combined with external sensing technology, this sensor has great application potential in the fields of biotechnology, medical diagnosis, and environmental protection.
