| Outline of Final Research Achievements |
In this study, as a basic study aiming at realization of a propagation type surface plasmon sensor capable of high sensitivity detection of high refractive index medium with a refractive index of 1.5 or more by using optical anisotropic GaN and metal wire grid structure, We fabricated and characterized the surface plasmon sensor using the Au thin film on the GaP substrate and the Au one dimensional diffraction grating on the glass substrate.
It was clarified that the medium with the refractive index up to 1.700 can be detected by using the surface plasmon sensor using Au one dimensional diffraction grating on the glass substrate. We also show that by improving sensitivity and FOM value, it becomes possible to realize a surface plasmon sensor using a GaN substrate excellent in chemical resistance.
