Fiber Bragg grating (FBG) is the most widely used optical fiber sensor due to its compact
size, high sensitivity, and easiness for multiplexing. Conventional FBGs fabricated by using …

Plasmonic immunosensors are usually made of a noble metal (in the form of a film or
nanoparticles) on which bioreceptors are grafted to sense analytes based on the …

Abstract Distributed Fiber Optic Sensing (DFOS) is one of the promising tools for structure
health monitoring. It can measure physical quantities (such as temperature, strain, and …

Applying fiber-optics on surface plasmon resonance (SPR) sensors is aimed at practical
