“…FOFPI sensors can be used in a variety of applications, primarily for temperature (Table 1), pressure (Table 2) and refractive index (Table 3), providing stable and compact solutions. In [39], the proposed sensor was based on a Myral polymer (commercially available), and MMF presented an easy way to fabricate micro-displacement sensors exhibiting a sensitivity of 24.1 nm/µm, while [40] proposed a compact reflection-based modal interferometer consisting of an SMF and a small piece of PCF (photonic crystal fiber) for nano-displacement with a sensitivity of 32 pm/nm.…”

In-fiber interferometric-based sensors are a rapidly growing field, as these sensors exhibit many desirable characteristics compared to their regular fiber-optic counterparts and are being implemented in many promising devices. These sensors have the capability to make extremely accurate measurements on a variety of physical or chemical quantities such as refractive index, temperature, pressure, curvature, concentration, etc. This article is a comprehensive overview of the different types of in-fiber interferometric sensors that presents and discusses recent developments in the field. Basic configurations, a brief approach of the operating principle and recent applications are introduced for each interferometric architecture, making it easy to compare them and select the most appropriate one for the application at hand.
