“…The sensitivity of the optical fiber laser sensor is 1.16 pm/με and the goodness of fit is 0.998. Remarkably, the proposed fiber laser sensor is better than those in previous reports using FBGs with respect to the sensitivity [31,34,36].…”

In this article, a precisely controlled, switchable thulium-doped fiber laser (TDFL) with high optical signal-to-noise ratio (OSNR) is proposed and demonstrated. A home-made multimode fiber Bragg grating (MMFBG) with multireflection peaks was used as an optical filter to select the desired lasing channel. Using a manually controlled fusion splicer, the axial misalignment was applied between the single mode fiber and the MMFBG to switch the output wavelength. In the experiment, the number of switchable lasing lines was up to 12, and the fluctuation of the center wavelength and output power was less than 0.03 nm and 0.67 dB, respectively. A maximum slope efficiency of 1.3% was obtained when the axial misalignment was 0 μm, and the OSNR was higher than 65 dB. In addition, the proposed fiber laser was used as an optical fiber laser sensor to quantify the strain applied on the MMFBG, and a sensitivity of 1.16 pm/με was obtained.

“…The introduction of the FBG can effectively prevent the cross-sensitivity of the FPI. In addition, Gao et al proposed a sensor based on few-mode fiber (FMF) and FBG in 2020 [ 118 ]. The sensor unit is composed of a segment of SMF and FMF dislocation splicing ( Figure 5 d).…”

Temperature, salinity, and pressure (TSP) are essential parameters for the ocean. Optical fiber sensors (OFSs) have rapidly come into focus as an ocean detection technology in recent years due to their advantages of electromagnetic interference, light weight, low cost, and no waterproof requirement. In this paper, the most recently developed TSP sensors for single parameter and multi-parameter TSP sensing and measurement based on different OFSs are reviewed. In addition, from the practical point of view, encapsulation methods that protect fibers and maintain the normal operation of OFSs in seawater, and the response time of the OFS, are addressed. Finally, we discuss the prospects and challenges of OFSs used in marine environments and provide some clues for future work.

“…The single mode-few mode-single mode (SFS) fiber structure filter is also a typical optical filter and has been widely used in fiber sensing in recent years [26][27][28][29][30][31]. In this paper, we will show that the SFS fiber structure filter can also work as an all-optical temporal differentiator.…”
