Paper Abstract

Optical fiber sensor based on extraordinary optical transmission (EOT) phenomenon is widely used in chemistry, biomedicine and other fields for its intense near-field enhancement effect and high sensitivity of dielectric environment. However, processing periodic nanohole arrays structure on the fiber end face requires complicated process or expensive microfabrication equipments, which limits the development of optical fiber sensor based on EOT phenomenon. Striving to solve this problem, this paper proposes the template transfer method to process metal periodic nanostructures on the fiber end surface, and further examines the influence of excitation angle on the localized surface plasma resonance(LSPR) and surface plasmon resonance(SPR) through grinding the fiber end surface into sloping structures with different angles. The experiment results show that when the Angle is 7°, resonance excitation of fiber sensor with periodic nanohole arrays structure performs the strongest, as well as sensors achieving optimal sensing ability.
