Abstract
This paper reviews presents a review of the current status and future prospects of plasmonic-effect-based No-Core Fiber (NCF) sensor technology. The discussion covers the basic principles of plasmonic effects, namely Surface Plasmon Resonance (SPR) and Localized Surface Plasmon Resonance (LSPR), the sensing mechanism of NCF, and the current status of plasmonic-based NCF sensor development. Plasmon-based NCF sensors have been widely applied in various measurement applications, with the majority of research focusing on refractive index sensors. Most studies still utilize SPR rather than LSPR, considering the technical challenges in controlling the size and shape of metal nanoparticles in LSPR. Nevertheless, LSPR provides design flexibility that enables precise tuning of nanostructure parameters to improve sensor sensitivity. Some potential development directions include optimizing sensor design to improve sensitivity and selectivity, developing more controllable and reproducible fabrication methods, and exploring new plasmonic materials. With the advancement of fabrication technology and characterization methods, it is expected that the technical challenges in developing plasmonic-based NCF sensors can be overcome. This advancement will facilitate broader applications across diverse fields, including chemistry, biosensing, and environmental monitoring.
