In this paper, optical fiber sensors, based on both surface plasmon resonance (SPR) and localized SPR (LSPR) approaches, have been successfully developed and cross-compared. The SPR sensor has been constructed by coating a thin layer of gold film on a piece of an optical fiber with the cladding havi...
