Oxygen sensor is an important technique in various applications including industrial process control, medical equipment, biological fabrication, etc. The reported optical fiber‐based configurations so far, using gas‐sensitive coating do not meet the stringent performance targets, such as fast response time and low limit of detection (LOD). Tin‐based halide perovskites are sensitive to oxygen with potential use for sensor applications. Here, the halide perovskite‐based oxygen optical fiber sensor by combining phenylethylammonium tin iodide (PEA2SnI4) and tilted fiber Bragg grating (TFBG) is demonstrated. The PEA2SnI4‐based oxygen optical fiber sensor is reversible at room temperature with a response time of about 10 s, and the experimental LOD approaches to an extremely low oxygen concentration of about 50 ppm. The as‐fabricated oxygen sensor shows a relative response change of 0.6 dB for an oxygen concentration increase from 50 ppm to 5% with good gas selection against NO2, CO, CO2, H2. This work extends the sensor applications of halide perovskites, providing a novel technique for rapid and repeatable oxygen gas detection at a low level.

“…This unique feature can then be used to perform accurate refractometric measurements in dilute gases and in thin films surrounded by air or other gaseous substances, in particular for hydrogen detection using palladium or palladium-gold coatings (Fig. 38) [185,360,361]. These devices have been shown to achieve faster response times (less than 20 seconds of stabilization time during association phase, and less than 30 seconds for that of dissociation phases) and improved deactivation resistance (higher than 99% per test cycle).…”

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.

“…With increasing demands of biomedical and biochemical detection technology, optical fiber sensing techniques have been attracting more and more attention in these fields due to their fast and simple test process. A vast number of researches about biochemical sensors in using LPGs and TFBGs have been reported [48][49][50][51][15][16][17][18]. Comparing with LPGs, Ex-TFGs have high Q factor and lower thermal crosstalk, which are more suitable for biochemical sensing.…”

The development of excessively tilted fiber gratings (Ex-TFGs) provides a new type of sensing device with high refractive index (RI) sensitivity, low thermal crosstalk and vector sensing property. Due to the asymmetric grating structure of Ex-TFG, the light in the core is coupled into high order forwardpropagating cladding modes and split into two orthogonal polarization states, resulting in dual-peak resonances in the transmission spectrum. The Ex-TFG also exhibits a non-circularly symmetrical near field distribution, which endows an exceptional orientation sensing capability. Benefitting from the unique mode coupling behavior, Ex-TFGs have been studied and developed for many different sensing applications, such as polarization dependent torsion and loading sensors, vector accelerometer and magnetometer, and a variety of low thermal crosstalk bio/chemical sensors.This paper will review the recent study and development of Ex-TFGs in terms of mode coupling mechanism, fabrication method, transmission and sensor characteristics and the novel applications in sensing areas.
