Plastic optical fiber (POF) sensor has been immensely developed for many sensing applications including physical and chemical/bio sensor. Since it offers the advantages of non-destructive, easy fabrication and installation, immunity to electromagnetic interference, compact, low fabrication costs and higher durability compare to silica fiber sensor. Tapered POF is one of the modified structures on POF by reducing its diameter and induces guided modes in the core to be evanescent modes. As a sensor, the tapered structure on POF increase the sensitivity of non-tapered POF. The number of tapers on optical fiber affect its characteristics as well. Hence, it is important to investigate the characteristic of tapered POF with the variation on number of tapers. In this paper, the spectral characteristic of symmetric double tapered POF (DT POF) was investigated. The fabrication of symmetric DT POF was conducted by reducing the core diameter using chemical process as described in. The core diameter and the length of the tapered were fixed at 0.45 mm and 1 cm, respectively. The distance between two tapers was varied from 1-3 cm. Transmission spectrum characterization of symmetric DT POF was measured at near infrared wavelength range (900-1600 nm) using a spectrometer by OTO-Photonics.

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.

Fiber optic sensors based on surface plasmon resonance (SPR) have demonstrated outstanding performance in biomedical, environmental monitoring, public safety, and other aspects, which provide powerful platforms for qualitative detection and quantitative analysis of molecular interactions. Among them, multichannel fiber optic SPR sensor has become a core tool in parallel detection scenarios due to the superiorities of compensating for nonspecific binding and environmental fluctuations and implementing multianalyte determination. The realization methods of multichannel sensing revolve around fiber microstructures, enhancement by materials, and hybrid fiber. The applications of multichannel fiber optic SPR sensors are demonstrated in sensing of liquid refractive index (RI), RI and temperature, biochemical molecules, and physical parameters. This review thoroughly analyzes and compares the structure, excitation effect, sensing performance, and the advantages and disadvantages of each type of multichannel fiber optic SPR sensor. Even though there are still some challenges, such as insufficient sensing channels and difficulty in fabrication, in their advancement, efforts in multidiscipline including developing high-performance sensitive films and innovating micro-nano fabrication processes will overcome these bottlenecks. Lastly, the future development directions of multichannel fiber optic SPR sensors from principle, structure, and material aspects are discussed.
