Fiber Optic Plasmonic Sensors: Past, Present and Future
نویسندگان
چکیده
We review various fiber optic sensors utilizing both the propagating and localized surface plasmon resonance techniques. The utilization of optical fibers in plasmon based sensing has provided several advantages in sensing of various physical, chemical and biochemical parameters. The article starts with a brief introduction of the propagating surface plasmon resonance (SPR) and localized surface plasmon resonance (LSPR), presents the review of some of the past studies on SPR and LSPR based state-of-the-art fiber optic sensors and finally ends with the future scope of the plasmonics based fiber optic sensors. In addition, we discuss some latest results on the plasmon enhanced whispering gallery mode sensors, which require tapered optical fibers for excitation. The present review may provide the researchers a rigorous and organized literature for the understanding of the basics, utility and trends of fiber optic plasmonic sensor in a chronological order.

متن کاملCOMPARISON OF DIFFERENT GLASS COMPOUNDS FOR INTRINSIC FIBER OPTIC TEMPERATURE SENSORS
Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...
