“…This structure was without the characteristics of rotational symmetry, which greatly reduced the fiber confinement loss and had a high sensitivity of 8300 nm/RIU. In addition, a novel PCF-SPR sensor with two orthogonally polarized core modes was designed to achieve the simultaneous measurement of the magnetic field and temperature [85]. Four annular microchannels coated with Ag-Ta 2 O 5 films were symmetrically distributed in PCF cladding.…”

This review introduces a micro-integrated device of microfluidics and fiber-optic sensors for on-site detection, which can detect certain or several specific components or their amounts in different samples within a relatively short time. Fiber-optics with micron core diameters can be easily coated and functionalized, thus allowing sensors to be integrated with microfluidics to separate, enrich, and measure samples in a micro-device. Compared to traditional laboratory equipment, this integrated device exhibits natural advantages in size, speed, cost, portability, and operability, making it more suitable for on-site detection. In this review, the various optical detection methods used in this integrated device are introduced, including Raman, ultraviolet–visible, fluorescence, and surface plasmon resonance detections. It also provides a detailed overview of the on-site detection applications of this integrated device for biological analysis, food safety, and environmental monitoring. Lastly, this review addresses the prospects for the future development of microfluidics integrated with fiber-optic sensors.

“…Liu et al [ 58 ] coated gold film in the large air holes and filled them with MF, while the small air holes were filled with PDMS and gold wires, which also realized the magnetic-field intensity sensing measurement free from temperature effects, as shown in Figure 5 d. Wang et al [ 59 ] connected a large core MMF to POF, where the surface of POF was coated with Ag film; then, the SPR channel under test was activated. Due to the air hole from the collapse effect in the MMF-POF welding process, the temperature sensitivity of SPR was weak and the effect of temperature was naturally eliminated, as shown in Figure 5 e. Gu et al [ 60 ] set up four microfluidic cavities in the fiber cladding, as shown in Figure 5 f. Ag-Ti 2 O 5 was evaporated in turn close to the fiber core, the upper and lower microcavities were filled with MF, and the left and right microcavities were injected with temperature-sensitive materials to excite the orthogonal SPR mode. This structure also achieves magnetic field measurement that eliminates the effect of temperature.…”

The fiber-optic surface plasmon resonance sensor has very promising applications in environmental monitoring, biochemical sensing, and medical diagnosis, due to the superiority of high sensitivity and novel label-free microstructure. However, the influence of ambient temperature is inevitable in practical sensing applications, and even the higher the sensitivity, the greater the influence. Therefore, how to eliminate temperature interference in the sensing process has become one of the hot issues of this research field in recent years, and some accomplishments have been achieved. This paper mainly reviews the research results on temperature self-compensating fiber-optic surface plasmon sensors. Firstly, it introduces the mechanism of a temperature self-compensating fiber-optic surface plasmon resonance sensor. Then, the latest development of temperature self-compensated sensor is reviewed from the perspective of various fiber-optic sensing structures. Finally, this paper discusses the most recent applications and development prospects of temperature self-compensated fiber-optic surface plasmon resonance sensors.

“…The d denotes the distance from the D-shaped surface to the PCF center. The dispersion relationships of gold and PCF substrate are determined by Drude model [34] and Sellmeier equation [35], respectively. The PCF center surrounded by six cladding air holes forms a light-guided core with high refractive index (RI) used for the light transmission.…”

We propose a kind of surface plasmon polaritons (SPPs)-assisted dual-V-type four-level composite system used for high-sensitivity weak magnetic field measurement. The SPPs are excited by a D-shaped photonic crystal fiber (PCF) deposited with gold nanowires, and are interacted with the above quantum emitter from the rubidium atomic vapor. In the presence of the external magnetic field, Faraday rotation symmetry is broken due to Zeeman effect, resulting in the polarization plane rotation when a linearly polarized probe field goes through the above quantum emitter. With the help of the coupled field and SPPs, Faraday magneto-optical rotation (MOR) are effectively regulated. The Rabi frequency of the coupled field (Ω c ), quantum interference degree (q), and phase difference (φ) between the applied fields show strong dependence on the MOR angle and magnetic field measurement sensitivity. The simulated results reveal that the maximum MOR angle and magnetic field sensitivity both damp with Ω c expanding and q reducing. The maximum dichroism-independent MOR angle of 89.97° is realized for φ = 0° (180°), and the magnetic field sensitivity of 10.88°/Oe is obtained in the sweeping range of −8.88–8.88 Oe for q = 0.99, being 2.66°/Oe higher than that in the absence of SPPs (q = 0). Most importantly, the output probe field with different polarization forms can be realized by adjusting the φ value. Hence, the proposed device exhibits the potential in the fields of weak magnetic field measurement and polarization control.
