“…Diverse temperature sensors based on optical fibers have been projected over the last few years [13][14][15]. These optical sensing platforms are aligned to different techniques, such as FBG [16,17], Surface Plasmon Resonance (SPR) [18,19], side-polished fibers [20,21], photonic crystal fibers (PCF) [22][23][24], fiber FP interferometers [25][26][27][28][29], and tapered fibers [30,31]. Of the two types of fibers-glass and plastic optical fiber (POF) [32,33] is considered particularly advantageous owing to its excellent flexibility, easy handling, great numerical aperture, large diameter, and the fact that plastic is able to resist smaller bend radii more than glass [33,34].…”

The use of sensors in the real world is on the rise, providing information on medical diagnostics for healthcare and improving quality of life. Optical fiber sensors, as a result of their unique properties (small dimensions, capability of multiplexing, chemical inertness, and immunity to electromagnetic fields) have found wide applications, ranging from structural health monitoring to biomedical and point-of-care instrumentation. Furthermore, these sensors usually have good linearity, rapid response for real-time monitoring, and high sensitivity to external perturbations. Optical fiber sensors, thus, present several features that make them extremely attractive for a wide variety of applications, especially biomedical applications. This paper reviews achievements in the area of temperature optical fiber sensors, different configurations of the sensors reported over the last five years, and application of this technology in biomedical applications.

Simultaneous Plasmonic Measurement of Refractive Index and Temperature Based on a D-Type Fiber Sensor With Gold Wires

This paper presents an optical fiber sensor that uses surface plasmon resonance (SPR) on metallic wires to directly and simultaneously measure both the refractive index and the temperature. The sensor is constituted by gold wires on a D-type fiber engineered, using numerical simulations based on the finite element method (FEM) to support plasmon modes with strong dependencies to either one of the measured parameters. In particular, the influence of the temperature on the structure of the plasmon modes results from contributions from the thermooptic effect in the fiber core and sensing layer, and phononelectron scattering along with electron-electron scattering in the metal wire. The performance of the sensor is evaluated in terms of its sensitivity and resolution.

“…Among the LOF technology platforms, “Lab-on-Tip” devices are particularly attractive because of the simplicity of the integration of the sensing material on the fiber tip [4]. The application of LOF approach to temperature sensing has been demonstrated using several measuring principles, like for example Fabry-Perot interferometers [5,6], Fiber Bragg gratings [7,8] or surface plasmon resonance [9,10]. Although often moderate sensitivities are reported, with resolutions of 0.55

Phosphors based on magnesium titanate activated with Mn4+ ions are of great interest because, when excited with blue light, they display a strong red-emitting luminescence. They are characterized by a luminescence decay which is strongly temperature dependent in the range from −50 ∘C to 150 ∘C, making these materials very promising for temperature sensing in the biochemical field. In this work, the optical and thermal properties of the luminescence of Mg2TiO4 are investigated for different Mn4+ doping concentrations. The potential of this material for temperature sensing is demonstrated by fabricating a fiber optic temperature microsensor and by comparing its performance against a standard resistance thermometer. The response of the fiber optic sensor is exceptionally fast, with a response time below 1 s in the liquid phase and below 1.1 s in the gas phase.
