Abstract

Surface plasmon resonance (SPR) sensors have been studied thoroughly for the past two decades. However, we found that the angular sensitivity in a prism-coupled SPR sensor can be as high as 500 deg/refractive index unit (RIU), which is two times higher than the sensitivity that has ever been achieved in previous studies. Such a high angular sensitivity can be fully achieved by simply choosing a proper low-index prism and a sufficiently large resonant angle for the light signal at an appropriate wavelength with an optimal metal film thickness. A feasible implementation of such an SPR sensor design concept was also proposed, and an even higher sensitivity of 600 deg/RIU can be achieved.
