“…Laser processing as the most popular application mainly involves four laser writing technologies according to different heating lasers: ultraviolet laser (UV laser) [ 41 , 42 ], excimer laser [ 43 ], femtosecond laser [ 31 ] and CO 2 laser [ 44 ], that can fabricate the specific fiber grating structures, grooving, and heating in optical fibers with different characteristics based on specific needs. At present, the most popular treatment methods widely used in fiber grating coupled SPR sensors are CO 2 lasers.…”

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.

“…For conventional UV-inscribed FBGs, the reflected spectrum of the sensor does not change significantly from room temperature to 400 • C, above which the grating loses its excellent sensing performances [4]. The gratings written in the boron-germaniumsilicon fiber, on the other hand, resist up to 400 • C [5,6], while direct-writing gratings resist up to 950 • C [7].…”

Metallurgical Aspects of Ni-Coating and High Temperature Treatments for FBG Spectrum Regeneration

The structural integrity of mechanical components is assessed by FBG sensors in many industrial fields. The FBG sensor has a relevant application at very high or low temperatures. To avoid the variability of the reflected spectrum and the mechanical properties degradation of the FBG sensor, metal coatings have been used to guarantee the grating’s integrity in extreme temperature environments. Particularly, at high temperatures, Ni could be a suitable selection as a coating to improve the features of FBG sensors. Furthermore, it was demonstrated that Ni coating and high-temperature treatments can recover a broken, seemingly unusable sensor. In this work, two main objectives were pursued: first, the determination of the best operative parameters to achieve the most compact, adherent, and homogeneous coating; second, the correlation between the obtained morphology and structure and the FBG spectrum modification, once Ni was deposited on the FBG sensor. The Ni coating was deposited from aqueous solutions. By performing heat treatments of the Ni-coated FBG sensor, it was investigated how the wavelength (WL) varied as a function of temperature and how that variation was caused by the structural or dimensional change of the Ni coating.
