“…Different configurations (multi-hole, three-hole, "grapefruit", etc.) were proposed for plasmonic generation by coating the core or the other holes with NPs, over the last millimeters or centimeters of the fiber, or by filling some of the holes with metal [55][56][57][58][59][60][61][62]. In all cases, the guiding geometry must be such that some part of the guided light (usually the evanescent tail of guided modes) interacts with a metal surface along part of the length only (otherwise there would be too much loss and no light would reach the detector).…”

This paper presents a brief overview of the technologies used to implement surface plasmon resonance (SPR) effects into fiber-optic sensors for chemical and biochemical applications and a survey of results reported over the last ten years. The performance indicators that are relevant for such systems, such as refractometric sensitivity, operating wavelength, and figure of merit (FOM), are discussed and listed in table form. A list of experimental results with reported limits of detection (LOD) for proteins, toxins, viruses, DNA, bacteria, glucose, and various chemicals is also provided for the same time period. Configurations discussed include fiber-optic analogues of the Kretschmann-Raether prism SPR platforms, made from geometry-modified multimode and single-mode optical fibers (unclad, side-polished, tapered, and U-shaped), long period fiber gratings (LPFG), tilted fiber Bragg gratings (TFBG), and specialty fibers (plastic or polymer, microstructured, and photonic crystal fibers). Configurations involving the excitation of surface plasmon polaritons (SPP) on continuous thin metal layers as well as those involving localized SPR (LSPR) phenomena in nanoparticle metal coatings of gold, silver, and other metals at visible and near-infrared wavelengths are described and compared quantitatively.

“…By engineering the geometric structure of the MOFs with various structural parameters, a maximum sensitivity of 21,700 nm/RIU has been achieved [71]. In this line, several different configurations, namely, three-hole, multi-core, grapefruit, and higher-order asymmetric MOFs have been demonstrated [72][73][74][75][76][77][78][79].…”

Recent Advances in Plasmonic Sensor-Based Fiber Optic Probes for Biological Applications

The survey focuses on the most significant contributions in the field of fiber optic plasmonic sensors (FOPS) in recent years. FOPSs are plasmonic sensor-based fiber optic probes that use an optical field to measure the biological agents. Owing to their high sensitivity, high resolution, and low cost, FOPS turn out to be potential alternatives to conventional biological fiber optic sensors. FOPS use optical transduction mechanisms to enhance sensitivity and resolution. The optical transduction mechanisms of FOPS with different geometrical structures and the photonic properties of the geometries are discussed in detail. The studies of optical properties with a combination of suitable materials for testing the biosamples allow for diagnosing diseases in the medical field.

The transmission losses and lengths of two polarized fundamental modes for a metal-coated eccentric core optical fiber (ECOF) are considered based on the finite-element method. Three typical thin metal films (Au, Ag, and Cu) are used and deposited on the walls of the cladding of ECOF. The variations of the transmission losses and lengths are investigated with different eccentricity, core radii, and metal film species. The numerical results indicate that the optical spectrum of a metal-coated ECOF can be tuned easily by changing the structure parameters of the fiber. The fundamental mode of metal-coated ECOF shows good polarization dependency. It is forecasted that the attenuation difference between the two polarization modes may be used to design an in-fiber polarizer.
