Abstract

A 44-pass fibre-optic surface plasmon resonance sensor that enhances detection sensitivity according to the number of passes is demonstrated for the first time. The technique employs a fibre-optic recirculation loop that passes the detection spot 44 times, thus enhancing sensitivity by a factor of 44. Presently, the total number of passes is limited by the onset of lasing action of the recirculation loop. This technique offers a significant sensitivity improvement for various types of plasmon resonance sensors that may be used in chemical and biomolecule detections.
