Paper Abstract

An integrated surface plasmon resonance (SPR) array sensor using wideband sources and a different incident angle with a single fluidic channel in order to increase the sensitivity is proposed and analyzed. The SPR reflectance was analyzed using the finite-difference time-domain gaussian source method. The maximum difference is shown at the incident angle of 24.6°. The sensitivity of the resonance shift used to change the refractive index of 1x10-3 is 51000 nm/RIU at the wavelength interrogation. The extremely small integrated SPR array sensor is a very attractive component because of its promise of a high level of sensitivity, its easy measurement process, and its ease of integration into a sensor system.
