SPR photo diode detector using transportation phenomenon of photon and electron coupling

We propose a Surface Plasmon Resonance (SPR) photodiode (PD) detector using transportation phenomenon of photon and electron coupling. Since SPR is usually measured by reflection intensity, a large space for measuring the intensity is required. Thus, we develop an SPR detector, which can detect an SPR condition without measuring the reflection intensity as shown in Figure 1(a). In this paper, we show that an SPR can be measured by using the sensor. And we verified the SPR transportation phenomenon of photon and electron coupling from experimental results.
