We have developed a measurement tool that has a new prism-coupler mechanism for measuring Surface Plasmon Polariton (SPP) propagations. The tool is composed of two sets of light sources and two sets of optical sensors, located on the holder arms, and a sample holder, located on the axis of the rotation. We independently varied the angle-of-incidence and the angle-of-reflection by controlling the four rotary stages with a personal computer. The SPP propagation length was estimated based on the amount of distortion in the profile of the reflected beam. The distortion ratios were 3.6% for p-polarized light and around 0% for the laser beam without reflection for Ag films. Our SPP propagation measurement tool is thus well suited for use in designing thin film materials or structures for plasmonic devices.
