Abstract:Multimode optical fiber is widely used because of its large core size, strong light-gathering ability, and remote on-line sensing ability in various environments. Due to the mode coupling and polarization loss, the signal curve obtained has wide full width at half-maximum (FWHM) and small peak value. Therefore, efficient methods to calculate the resonant wavelength are required. This paper presents a method to process the surface plasmon resonance curve (SPR) based on the Fourier series fitting. The calculated resonant wavelength is obtained with one-dimensional extremum-search method.
