Optofluidic, as an emerging technology that combines photons and microfluidics, has become a powerful, intelligent, and universal sensing platform in the field of bio-chemical sensing. Optical fiber optofluidic (OFOF), as a branch of optofluidic technology, has stimulated a host of remarkable achievements in the field of bio-chemical sensing due to its superiority of compact structure, immunity to electromagnetic interference, low sample consumption, high sensitivity, and real-time dynamic response. In this paper, an overview of OFOF bio-chemical sensors is presented. The OFOF system architectures are introduced and some advanced functional materials and coating technologies that can be utilized in the OFOF sensing platform to achieve high-performance biochemical sensing are summarized. Research progress and current status of OFOF bio-chemical sensors based on various sensing mechanisms are summarized and analyzed, with emphases on their sensing principles, sensing structures, sensing applications, advantages, and disadvantages. Lastly, the existing challenges and future development trends of OFOF biochemical sensors are briefly discussed.

“…where F SR s and F SR r are the FSRs of the reference interferometer and the sensing interferometer, respectively. If n s and n r are closed to each other but not equal, the Vernier effect would be facilitated [24], [25]. As a result, the transmission spectrum would have a series of additional periodic fringes with different amplitudes.…”

A unique type of refractive index (RI) sensor is proposed using a dual Mach-Zehnder interferometer (MZI) structure based on side-hole fibers (SHFs). The MZI structure contains two single-mode fibers (SMFs), two coreless fiber (CLF) sections and an SHF section, which are spliced together in the order of SMF-CLF-SHF-CLF-SMF. The SMFs and the CLFs enable light lead in/out and beam splitting/combining, respectively. As a special feature of the structure, one hole of SHF is exposed for liquid filling and to form two MZIs as well. Three types of sensors are fabricated, namely S1, S2 and S3. Numerical simulation and experimental studies have been conducted to characterize the sensing performance. The RI sensitivity of the S1 using the ∼550 μm long SHF section reaches 14,000 nm/RIU. When a shorter SHF section is used in S2, the detectable RI range is broadened due to larger FSR. When the closed hole of SHF in S3 is filled with liquid to introduce the Vernier effect, the sensitivity can be further enhanced to over 44,000 nm/RIU (i.e., Refractive Index Unit), which corresponds to the detection limit at the level of 1.0 × 10 −5 RIU. This sensor design is original and easy to package, which gives it potential for label-free biochemical analyses.

“…Hence, the research on the measurement of gas pressure has become a focus of attention in recent years, and a variety of gas pressure sensors have been proposed and developed by researchers in succession. With the characteristics of light weight, high temperature resistance, and anti-electromagnetic interference, fiber-based gas pressure sensors [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16] have stood out from the numerous gas pressure sensors and are well suited for gas pressure measurement in various industrial equipment.…”

“…Nowadays, according to the working principle, the typical fiber-based gas pressure sensors can be mainly divided into two categories: Optical fiber grating-based gas pressure sensor [1,2,3] and optical fiber interferometer-based gas pressure sensor [4,5,6,7,8,9,10,11,12,13,14,15,16]. For the optical fiber grating-based gas pressure sensor, its sensor head is typically constituted by a fiber grating, such as the long-period grating (LPG) inscribed by periodically inflating photonic crystal fiber (PCF) [1] or hollow-core photonic bandgap fiber (HC-PBF) [2], and the fiber Bragg grating (FBG) written in a bare fiber [3].…”

“…Compared with the optical fiber grating-based gas pressure sensor, the optical fiber interferometer-based gas pressure sensor is more widely used due to its inherent characteristics of simple structure and high sensitivity. So far, the optical fiber interferometers used in the gas pressure sensors mainly contain Mach–Zehnder interferometers (MZI) [4,5,6,7] and Fabry–Perot interferometers (FPI) [8,9,10,11,12,13,14,15,16]. The MZIs constituted by twin-core fiber [4], inner air-cavity in single mode fiber (SMF) [5], dual side-hole fiber (DSHF) [6], and HC-PBF [7] have been applied in the field of gas pressure detection, and yet for the above MZI-based gas pressure sensors [4,5,6,7], it is essential to employ a femtosecond laser to drill micro-channel on the interferometer structure, which sharply increases the cost.…”

A novel temperature-independent gas pressure sensor based on a reflective fiber Lyot filter is presented in this paper. The reflective fiber Lyot filter is simply consist of a fiber polarizer and a segment of hollow-core photonic bandgap fiber (HB-PCF). The HB-PCF plays the role of birefringent cavity in the reflective fiber Lyot filter and works as the sensor head in the gas pressure sensor. Experiment results show that the responses of the sensor to gas pressure and temperature are 3.94 nm/MPa and −0.009 nm/°C, indicating that the proposed gas pressure is sensitive to gas pressure rather than temperature. Coupled with the advantages of simple structure, easy manufacture, high sensitivity and temperature independent, the proposed reflective fiber Lyot filter-based gas pressure sensor holds great potential application in the field of gas pressure monitoring.
