Paper Abstract

A surface plasmon resonance (SPR) sensor on an optical fiber endface with metallic rectangular slit array structure is presented. The finite-difference time-domain (FDTD) method was utilized to study the influence of structural parameters on the transmission spectrum and the refractive index (RI) sensing characteristic based on the two transmission peaks. The proposed sensor is compact and has the potential to be used in biomedical applications, having two transmission peaks with a sensitivity of 1209 and 500 nm per refractive index unit (RIU) respectively.
