Outline of Final Research Achievements

In this study, an electron field emitter array based on plasmon-resonant excitation is studied and developed. In order to excite highly-densed field emitters individually, radially-polarized excitation is found to be effective. Therefore, an array of radial polarizer array is needed. To realize this, a micro optical retarder based on gold nanograting is studied and successfully developed. This structure has very high transmittance over other plasmonic nanooptical devices, because of its higher aspect ratio.
