Modelling and characterisation of surface plasmon based sensors for the detection ofE. coli

Fiber-Optic Chemical Sensors and Biosensors (2008–2012)

“…A fiberoptic SPR immunosensor for E. coli bacteria has been modeled by the finite-element method. 178 The complex propagation characteristics, the formation of the coupled supermodes, and power fraction in the different regions, modal loss, differential loss, and coupling length were calculated, and the effect of the outer RI on the inner and outer surface-plasmon modes investigated with the aim to achieve the best coupling and sensitivity. The authors also show that the design of SPR fiber-optic sensors can be optimized, with respect to the maximal field penetration in the outer medium.…”

Optical Fiber Humidity Sensor Based on Lossy Mode Resonances

“…Among them, the utilization of optical fiber in the design and fabrication of sensors added new and important advantages, such as simplified design, miniaturization, multiplexing capability, electromagnetic immunity, etc [2]. Different techniques have been used to develop new optical fiber sensors, such as fluorescence [3], interferometry [4], fiber Bragg gratings (FBGs) [5], long fiber gratings (LPGs) [6], photonic crystal fiber (PCB) [7] or surface plasmon resonance (SPR) [8].…”
