“…In order to avoid cross sensitivity among the measurands, for example temperature dependency in RI measurements, the right solution is the design of an appropriate transducing mechanism that is selective in nature towards the measurement of a desired perturbation [15][16][17][18][19][20][21][22][23]. Some designs include the use of PCF to reduce temperature dependency [24] in combination with short taper segments for excitation of multiple modes [25], peanut structures [26] etc. The majority of current research is focused on dual-parameter sensors, while three or more is quite rare due to the very complex design and the need for advanced algorithms for signal processing, also posing the question of cost compared to multiplexed individual sensors.…”

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.

“…For example, MZIs were reported in dual-parameter sensors for strain and temperature measurements. 22,40 In Ref. 40, a single MZI is created by "sandwiching" a straight section of a polarization maintaining fiber between two peanut mode coupling structures and standard SMFs, as illustrated in Fig.…”

Needs for sensor miniaturization, versatile sensing solutions, and improved measurements' performances in difficult operating environments have recently driven considerable research in optical fiber sensor for multiparameter measurements. Multiparameter sensors not only enable new sensors' functionalities, but can also improve achievable measurement performances for some frequently measured parameters considerably. This study provides a review of work in the field of miniature fiber-optic sensors that allows independent and simultaneous measurements of two or more different physical or chemical parameters. Sensor designs and corresponding signal processing schemes are reviewed and compared.
