Paper Abstract

A Fabry-Perot interference enhanced surface plasmon resonance (SPR) sensor was designed and analyzed numerically. In this paper, a micro-fluidic channel with two parallel interfaces formed on the metal film of an angularinterrogated SPR sensor was employed. The shift of the narrow reflection dips as a function of the refractive index change of the fluid (angular sensitivity Sθ ) was very high. Meanwhile, the angular dip width δθFWHM was very narrow (<0.01°) and can be adjusted by changing the thickness of the resonant cavity. The corresponding intrinsic sensitivity IS = SθθFWHM higher than 105 RIU-1 around the resonant angle can be achieved.
