Abstract

Wavelength, linewidth and divergence angle of light source are crucial in high precision SPR measurement and investigated respectively in this paper. Theoretical modeling and simulation results show that the resonance angle is more sensitive to short wavelength, and both linewidth and divergence angle broaden and reduce the depth of the resonance peak. Increment of linewidth and divergence angle can also result in a larger resonance angle.
