Abstract
ABSTRACT Surface plasmon resonance (SPR) and surface plasmon polariton (SPP) is substantially developing optical sensing approaches that have been working in a wide range of applications, such as biological and chemical analyte detection, bioimaging, food safety, and environmental monitoring to security. Recently, optical fiber-based Surface plasmon resonance (SPR) sensors has gained much attention due to the invention of Photonic crystal fiber (PCF) and microstructured optical fiber (MOF) which offer compact size and light regulatory competencies in unmatched ways. Moreover, the field of sensing has witnessed another type of plasmonic sensors which are based on metal-insulator-metal (MIM) waveguide structure utilizing surface plasmon polariton (SPP) phenomena. This review paper provides an insight into the technological growths in plasmonic sensors based on optical fibers and the MIM platform. We believe that this paper is one of its kind which provides a diverse range of novel plasmonic sensor structures to its readers.
