Abstract

Current research on Surface plasmon polaritons (SPPs) is widely spread to surface adsorption, surface roughness and other related phenomena. It has also been used in the chemical and biological high-precision detection fields. More and more high-precision sensors have been created. Supercontinuum (SC) is a laser source with advantages as broad and flat spectra, high brightness and good coherent characters. By researching the SC laser source based surface plasmon resonance (SPR) effect, we can get a more comprehensive reflection of the SPR effect from factors as the light intensity reflectivity and the phase change. The SC laser source based SPR effect is a subject with important theoretical and practical significance. The testing principles and testing methods of the SPR effect in the installations with the Au-coated prism structure were studied. Using a SC laser, the wavelength-scanning and angle-scanning methods can be carried out in one system. The SC laser source based SPR effect in the installations with the Au-coated prism structure was tested. The SPR effect sensors based on SC were designed and realized. The theoretical results matched with the experimental results. Through the relation between the refractive index and the resonance wavelength, we could demarcate different substances.
