“…The results showed that it provided low temperature dependence to measure low temperature cross-sensitivity. Qi et al [62] used a single-mode fiber-hollow fiber (5 mm) -single-mode fiber structure to measure temperature. The temperature sensitivity was 21.30 pm= C which was much higher than Coelho's value.…”

& Modal interference is a major topic in optical fiber sensing technology that has been applied to measure temperature, refractive index, curvature, displacement, strain, humidity, pH, and other parameters. In this article, basic sensing principles for the development of modal interferometers are introduced based on core-cladding and core modes. The structures, principles, and applications of the sensors are comprehensively reviewed and potential and future prospects are discussed.

“…Many researchers focus on liquid glucose concentration measurement [12]- [14] or gas detection [15], however, few researches have reported about the temperature sensor based on fiber-optic SPR configuration. Though some SPR sensors based on photonic crystal fibers [16] or hollow fibers [17] with liquid core show their great potential of temperature sensing, it is difficult to manufacture and realize in practical experiment.…”

A fiber-optic surface plasmon resonance (SPR) sensor for temperature detection has been proposed by utilizing a thermosensitive liquid as the intermediate and combining with the fiber SPR structure. The sensing element of the sensor has been fabricated by packaging the fiber probe coated with a silver layer into a capillary filled with thermosensitive anhydrous ethanol. This packaging can protect the metal layer from oxidation and damage. Moreover, this proposed sensor achieves a sensitivity of 1.5745 nm/°C, which is much higher than that of the traditional fiber SPR sensor according to the comparative experiments.Index Terms-Capillary packaging, ethanol, fiber-optic sensors, surface plasmon resonance (SPR), temperature measurement.
