“…In the same year, Jin J. [110] proposed a method for correcting calculated strains based on the Frenet-Serret equations. This method can be used to correct axial strain errors, specifically errors [111,112] induced by the twisting of the fiber itself, thereby enhancing the accuracy of fiber shape sensing.…”

The rapid development of information and communication technology has driven the demand for higher data transmission rates. Multi-core optical fiber, with its ability to transmit multiple signals simultaneously, has emerged as a promising solution to meet this demand. Additionally, due to its characteristics such as multi-channel transmission, high integration, spatial flexibility, and versatility, multi-core optical fibers hold vast potential in sensing applications. However, the manufacturing technology of multi-core fiber is still in its early stages, facing challenges such as the design and fabrication of high-quality cores, efficient coupling between cores, and the reduction of crosstalk. In this paper, an overview of the current status and future prospects of multi-core fiber manufacturing technology has been presented, and their limitations will be discussed. Some potential solutions to overcome these challenges will be proposed. Their potential applications in optical fiber sensing will also be summarized.

“…As a result, a complete model of the local curvatures has been proposed, as can be seen in Eq. (15). Here it is clear that the shifts of the Bragg wavelength caused by the bending can be distinguished from those caused by the temperature, the tension/compression and the torsion, 15), represents the structural parameters of the triplet, which can be calibrated using the method which will be described in Section 4.1.…”

“…Such a configuration is the simplest theoretically, which can be used in estimating the magnitude of the curvature and the direction of the bending, while excluding the effects of other disturbances such as temperature-induced Bragg wavelength shifts. Some recent studies have added a further FBGs (placed in the centre of the triplets) [13][14][15][16][17][18][19], to provide more detailed information to include in the model, especially information on the torsional strain [14,18] and axial tension [15,20]. The FBGs in the centre allow independent compensation for temperature and axial strain, allowing the torsion alone to be calculatedthis being extremely useful in those applications where knowing the tip position and pose is critical despite its high cost.…”

“…In such case, the separate measurement tells the user at which temperature the refractive index was measured. This is routinely done with TFBGs where the core mode resonance is inherently insensitive to changes occurring solely outside the core mode field cross section, as long as the group index contribution is taken into account in the measurements of the other resonances [14,[207][208][209][210]. Although temperature sensing is already very well addressed by SMF sensor technologies, it is discussed here for two reasons: applications at higher temperatures than those of common FBG technologies and dealing with the cross-sensitivity to temperature of multimodal sensors for other applications.…”

The aim of this paper is to provide a comprehensive review of mode-division and spatial-division optical fiber sensors, mainly encompassing interferometers and advanced fiber gratings. Compared with their single-mode counterparts, which have a very mature field with many highly successful commercial applications, multimodal configurations have developed more recently with advances in fiber device fabrication and novel mode control devices. Multimodal fiber sensors considerably widen the range of possible sensing modalities and provide opportunities for increased accuracy and performance in conventional fiber sensing applications. Recent progress in these areas is attested by sharp increases in the number of publications and a rise in technology readiness level. In this paper, we first review the fundamental operating principles of such multimodal optical fiber sensors. We then report on the theoretical formalism and simulation procedures that allow for the prediction of the spectral changes and sensing response of these sensors. Finally, we discuss some recent cutting-edge applications, mainly in the physical and (bio)chemical fields. This paper provides both a step-by-step guide relevant for non-specialists entering in the field and a comprehensive review of advanced techniques for more skilled practitioners.
