Abstract
A novel surface plasmon resonance (SPR) sensor based on the multihole optical fiber with TiO2 layer is proposed and numerically characterized. The finite element method(FEM) is used to analyze the characteristics of the SPR sensor. The effects of the pitch between air holes, the thicknesses of the gold film and titanium dioxide layer on the sensor characteristics are investigated, and the sensitivity of proposed sensor is also given. The results indicate that when the thickness of gold film increases, the resonance wavelength shifts to longer wavelength, and the resonance peak broadens. The spectral tuning of the plasmon resonance can be more efficiently realized by changing the TiO2 layer thickness. The maximal refractive-index resolution of the proposed sensor for aqueous analytes is 5×10-5.
