A Review of advancements (2007-2017) in plasmonics-based optical fiber sensors

The present review summarizes the progress made in the area of plasmonics-based fiber optic sensors during the last decade (2007-2017). The review is in continuation with the previous review focused on the developments made in the above area during the timeframe of almost 25 years (i.e., 1990-2006). In addition, other important reviews are also discussed in order to widen the scope of the work. This work is focused on review of four types of plasmonics-based optical fiber sensors viz., single mode fiber, multimoded fiber, microstructured fiber, localized surface plasmon resonance (LSPR), and use of two-dimensional (2D) materials such as graphene, MoS2 etc. The structures, performance parameters, and results related to some important works have been discussed. Based on the present state-of-the art, the future scope and related fields have been discussed.
