“…16.6c, an SPR fiber sensor with uniform metal coated U-shaped probe is adopted. The bending radius in U-shaped probe makes it possible to tune the sensitivity of the probe [17]. Furthermore, one-side metal coated fibers with and without remaining cladding, and structures with modified fiber tips such as flat or angled structures have been proposed [18,19].…”

We overview the micro-and nano-structured optical fiber sensors, directly associated with surface plasmon resonance (SPR) sensing. Fiber sensors combined with SPR technologies offer a new route to improving the sensing capability. Various approaches have been exploited and optimized. For example, D-shape, cladding-off, and tapered fiber structures as well as dielectric or metallic gratings have been introduced. These micro-and nano-structured SPR fiber sensors have received much attention due to their high sensitivity, sensor miniaturization, and the flexibility of optical fibers. Key issues for fiber SPR sensors are low loss and high overlap with sensing medium. These fiber sensors with the use of SPR have been continually studied for chemical and bio-sensing. In this chapter we will review the current status of these micro-and nano-structured optical SPR fiber sensors.

“…It was concluded that the sensitivity of the sensor is maximum when the taper profile is exponential linear. Further, a U-shaped fiber optic SPR sensor was theoretically studied for the enhancement of sensitivity [49]. In both the cases, the tapering and U-shaped probes, an enhancement in the strength of coupling of the evanescent field with surface plasmons takes place, which is responsible for the increase in the sensitivity.…”

Abstract: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.
