Research Advances on Fiber-Optic SPR Sensors with Temperature Self-Compensation

Abstract

The fiber-optic surface plasmon resonance sensor has very promising applications in environmental monitoring, biochemical sensing, and medical diagnosis, due to the superiority of high sensitivity and novel label-free microstructure. However, the influence of ambient temperature is inevitable in practical sensing applications, and even the higher the sensitivity, the greater the influence. Therefore, how to eliminate temperature interference in the sensing process has become one of the hot issues of this research field in recent years, and some accomplishments have been achieved. This paper mainly reviews the research results on temperature self-compensating fiber-optic surface plasmon sensors. Firstly, it introduces the mechanism of a temperature self-compensating fiber-optic surface plasmon resonance sensor. Then, the latest development of temperature self-compensated sensor is reviewed from the perspective of various fiber-optic sensing structures. Finally, this paper discusses the most recent applications and development prospects of temperature self-compensated fiber-optic surface plasmon resonance sensors.

Highly sensitive plasmonic sensors and biosensors realized via modified specialty optical fibers

“…In the last years, the classic geometries of sensors based on SPR have been adapted for optical fibers (both extrinsic and intrinsic configurations), thus providing a simple approach to low-cost plasmonic sensing [4][5][6][7]. For instance, polymer optical fibers (POFs) are particularly advantageous due to their excellent flexibility, easiness of manipulation, great numerical aperture, large diameter and, last but not least, to the fact that plastic can withstand smaller bend radii than glass.…”

Sequential Dual Coating with Thermosensitive Polymers for Advanced Fiber Optic Temperature Sensors

“…Optical-fiber-based sensors are becoming increasingly mature and in greater demand in the fields of energy, biotechnology, biomedicine, superconducting magnets, automotive technology, aerospace, healthcare, and civil engineering [ 1 , 2 , 3 , 4 , 5 , 6 ]. These sensors have been extensively researched due to their advantages, such as passive operation, ease of fabrication, compact size, resistance to corrosion, remote sensing ability, capacity for distant sensing, and resistance to electromagnetic interference [ 7 , 8 , 9 , 10 , 11 ].…”

Temperature and salinity sensing characteristics of embedded core optical fiber based on surface plasmon resonance

“…Zhao et al developed a temperature self-compensating optical fiber SPR to measure temperature changes. Its application and development prospect are also expounded [ 18 ].Zhao Yong et al also studied a new type of optical fiber reflector probe to detect temperature, salinity and depth at the same time. Photonic crystal (PCF) is selected as the excitation field.…”
