The Antiresonant Reflecting Optical Waveguide Fiber Sensor

Abstract

In this chapter, the optical fiber sensors based on antiresonant reflecting optical waveguide have been introduced, including the single layer, double layers, double resonators, and hybrid mechanism. Various optical fiber sensors based on antiresonant reflecting optical waveguide have been introduced in this chapter with different working principles, including the fiber optic vibration sensor, humidity sensor, strain sensor, temperature sensor, magnetic field sensor, biosensor, etc. Especially, many long-standing challenges in the fiber optic sensor can be solved through the working principle of the antiresonant reflecting optical waveguide, including the temperature cross-talk compensation, distribution localization, optofluidic biosensing, etc. In general, the optical fiber sensors based on antiresonant reflecting optical waveguide have advantages, such as compact structure, high sensitivity, large dynamic range, and high stability, which appear to have potential applications in researches of structure health monitoring, oil exploiting, and biology detection.

Optical Fiber Sensors for Biocide Monitoring: Examples, Transduction Materials, and Prospects

“…Figure shows the different guiding mechanisms of photonic band gap (PBG), anti-resonant reflecting optical waveguide (ARROW), and surface plasmons (SPR).

“…The physical principle of ARROW applies to the light that does not meet the resonance condition and is confined to the low RI fiber core for transmission. 134 OFS can be primarily divided into two main types, intrinsic or extrinsic. Intrinsic OFS are sensors where there is no external recognition center and the optical fiber itself detects an external change (the measurand modifies some parameter of the fiber).…”
