Abstract

This study numerically and experimentally demonstrates the enhancement of phase detection sensitivity of a grating-coupled surface plasmon resonance (GCSPR) sensor by using incident light at a nonzero azimuth angle. Phase detection measurements were performed using an electro-optic heterodyne interferometer. The experimental results show that when the GCSPR sensor was rotated azimuthally by 0° and 58°, the phase detection sensitivities were approximately 3.2 ×10^-7 RIU and 5.5×10^-8 RIU, respectively. The nonzero azimuth angle was found to enhance the sensor sensitivity by a factor of 5.87 relative to the zero azimuth angle.
