已经开发了一种新型的波导耦合棱镜装置作为表面等离子体共振传感器。通过在棱镜上以这种顺序将Ag，Sio2和Au薄膜沉积的AG，Sio2和Au薄膜制造。该设备在光反射曲线中表现出急剧的吸收，这不仅是由于电场平行于反射平面（P-波）平行的偏振光，而且与垂直于反射平面（S-WAVE）的那个相似。菲涅尔公式很好地预测了P和S波的实验反射曲线。前者和后一种吸收是由于表面等离子体共振以及通过金属/SIO2边界的重复吸收通过波导传播光的衰减引起的。 （c）2000 Elsevier Science S.A.保留所有权利。
A novel waveguide-coupled prism device as a surface plasmon resonance sensor has been developed. The waveguide was fabricated by depositing Ag, SiO2, and Au thin films in this order on a prism. The device demonstrated a sharp absorption in the light reflectance curve due not only to the insertion of polarized light where electric field was parallel to the reflection plane (P-wave) but to that perpendicular to the reflection plane (S-wave). The experimental reflectance curves for both P- and S-waves were well predicted by the Fresnel formulas. The former and the latter absorptions are due to surface plasmon resonance and the attenuation of propagating light through the waveguide by the repetitive absorption at the metal/SiO2 boundary, respectively.
