“…Because of the grating's helical construction, clockwise or anticlockwise twisting can shorten or lengthen the period of grating, causing the resonance wavelength to shift in a different direction. Therefore, HLPG can be effectively applied in the fields of temperature, torsion, and refractive index sensors [7,15,17,18,33,[40][41][42][43]. Li analyzed the effects of LPG and intermodal interference in chiral twisted single-mode fibers (CTSMF) [44].…”

“…An improved HLPG method was proposed by Zhao to achieve the real-time measurement of multiple parameters [7]. To further enhance sensitivity, a fiber taper was introduced in a twisted structure [15]. The experimental results show that the intensity of the transmission peaks varies inversely when the fiber is twisted in different directions.…”

“…Scientists have used theories such as spiral Bloch theory [9], mode coupling theory [10], and the photoelasticity effect [11] to explain it. Compared with traditional fiber modification methods, twisted fibers provide new features and applications in information capacity expansion [12,13], fiber lasers [9], amplifiers [14], and sensors [7,15,16].…”

With an increase in the volume of information exchange and perception, the demands for intelligent, miniaturized, and integrated optical devices for information acquisition are also increasing. As the core component of optical networks for transmitting information, further optimization of their structural characteristics to generate richer optical characteristics and apply them to information exchange and optical field control has become a key research hotspot. The introduction of chiral twist characteristics has led to new phenomena and applications in optical field transmission and the transformation of traditional optical fibers or microstructured optical fibers (MOF). Therefore, this review mainly begins with the principle of chiral optical fibers, introduces their preparation and latest application scenarios, and finally discusses their potential future development prospects.

Optical fiber sensors based on tapered optical fiber (TOF) structure have attracted a considerable amount of attention from researchers due to the advantages of simple fabrication, high stability, and diverse structures, and have great potential for applications in many fields such as physics, chemistry, and biology. Compared with conventional optical fibers, TOF with their unique structural characteristics significantly improves the sensitivity and response speed of fiber-optic sensors and broadens the application range. This review presents an overview of the latest research status and characteristics of fiber-optic sensors and TOF sensors. Then, the working principle of TOF sensors, fabrication schemes of TOF structures, novel TOF structures in recent years, and the growing emerging application areas are described. Finally, the development trends and challenges of TOF sensors are prospected. The objective of this review is to convey novel perspectives and strategies for the performance optimization and design of TOF sensors based on fiber-optic sensing technologies.

A fiber-optic torsion sensor based on a helical two-core fiber (HTCF) is proposed and experimentally demonstrated for simultaneously measuring torsion angle and torsion direction. The sensor consists of a segment of HTCF and two single-mode fibers (SMFs) forming a Mach–Zehnder interferometer (MZI). The helical structure is implemented by pre-twisting a 1 cm long two-core fiber (TCF). The performance of the sensor with pre-twisted angles of 180°, 360°, and 540° is experimentally analyzed. The results show that the sensor can realize the angular measurement and effectively distinguish the torsion direction. It is worth noting that the sensor has maximum sensitivity when the pre-twist angle is 180 degrees. The obtained wavelength sensitivities of torsion and temperature are 0.242 nm/(rad/m) and 32 pm/°C, respectively. The sensor has the advantages of easy fabrication, low cost, compact structure, and high sensitivity, which is expected to yield potential applications in fields where both torsion angle and direction measurements are required.
