“…This is because the refractive index of the epoxy resin is bigger than that of the single mode fiber and the thermosensitivity coefficient of the epoxy resin is negative. 12 The SMSR of the FBG as a function of the temperature is shown in Fig. 3.…”

A fiber sensor for simultaneous measurement of temperature and strain based on a fiber Bragg grating (FBG) with the pigtail fiber covered with epoxy resin is presented. The side mode suppression ratio of the FBG will vary with the temperature due to the Fresnel reflection from the interface between the pigtail fiber and the epoxy resin whose refractive index is sensitive to the temperature. The sensor is also capable of simultaneous measurement temperature and strain by combining the Bragg wavelength shift characteristics as the temperature and strain of the FBG.

“…Fiber rolling and temperature loss mechanisms in POF have been reported. POFs show a great potential for short link communications and sensing operations [9, 10]. It was shown that intensity modulation technique can be used in a simple design in order to obtain information about fiber rolling losses in a rolled fiber.…”

Fiber bending and temperature loss mechanisms in plastic optical fibers are reported.A simple arrangement is used to monitor the fiber bending and temperature by output power variation. Powers in the fibers in bend‐free situation at room temperature and under rolling deforming force at different water bath temperatures (20–60°C) are measured and compared. Reported arrangements can be used as a temperature sensor. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:82–86, 2013; View this article online at wileyonlinelibrary.com.

“…Most importantly, among the different types of temperature sensors, optical fiber temperature sensors have successfully replaced traditional sensors owing to their distinctive advantages, including stability, immunity to electromagnetic interference, reusability, durability against stringent environments, high sensitivity, wide dynamic range, multiplexing capability, and fast response in a non-electrical operation [3,4]. A variety of optical fibers have been utilized in the field of optical fiber temperature sensors such as fiber Bragg gratings (FBGs) [2,[4][5][6], long period gratings (LPGs) [7][8][9], hollow core fibers (HCF) [10,11], multimode interference-based optical fibers (MMF) [12], and micro-bend fibers coupled with thin films [13,14].…”

The exploration of novel polymers for temperature sensing with high sensitivity has attracted tremendous research interest. Hence, we report a polystyrene-coated optical fiber temperature sensor with high sensitivity. To enhance the temperature sensitivity, flat, thin, smooth, and air bubble-free polystyrene was coated on the edge surface of a single-mode optical fiber, where the coating thickness was varied based on the solution concentration. Three thicknesses of the polystyrene layer were obtained as 2.0, 4.1, and 8.0 μm. The temperature sensor with 2.0 μm thick polystyrene exhibited the highest temperature sensitivity of 439.89 pm °C−1 in the temperature range of 25–100 °C. This could be attributed to the very uniform and thin coating of polystyrene, along with the reasonable coefficient of thermal expansion and thermo-optic coefficient of polystyrene. Overall, the experimental results proved the effectiveness of the proposed polystyrene-coated temperature sensor for accurate temperature measurement.
