Optical fiber sensors based on surface plasma technology have many unique advantages in specific applications such as extreme environmental monitoring, physical parameter determination, and biomedical indicators testing. In recent decades, various kinds of fiber probes with special structures were developed according to special processing such as tapering, splicing, etching, fiber balls, grating etc. In this paper, the fabrication technology, characteristics, development status and application scenarios of different special optical fiber structures are briefly reviewed, including common processing equipment. Furthermore, many special novel optical fiber structures reported in recent years are summarized, which have been used in various kinds of plasmonic sensing work. Then, the fiber-plasmonic sensors for practical applications are also introduced and examined in detail. The main aim of this review is to provide guidance and inspiration for researchers to design and fabricate special optical fiber structures, thus facilitating their further research.

“…However, fiber sensing systems based SPR principle need complex technology and high price. In 2021, Shouhuan Zhou et al from SiChuan University designed a tapered fiber sensor composed of two micro spheres [7]. By controlling the discharge time, current intensity, and advance distance, two microspheres can be generated in the fused part of two single mode fibers (SMF).…”

A novel temperature fiber sensor based on the multi-thin-no-thin-multi fiber (MTNTM-F) with Mach-Zehnder interference was presented. By comparing the interference spectra of the multi-thin-multi fiber and MTNTM-F, the MTNTM-F with more available dips and greater extinction ratio was selected. By simulating the energy distribution in the fiber, it was proved that there was a lot of energy in the cladding, which was beneficial to the interaction between the light and the external material. In order to improve the temperature sensitivity of the sensor, polydimethylsiloxane with large thermo optic coefficient and thermal expansion coefficient was selected to coat the fiber. Identical temperature sensing experiments were performed for untreated and coated fibers. The temperature sensitivity changed from 25.38 pm °C−1 to 65.24 pm °C−1, which was a 2.56 times improvement, and an ideal temperature stability was demonstrated. At the same time, an anti-turbulence adjunct experiment was conducted to investigate the ability of the sensor to avoid turbulence cross sensing.
