The authors present a plasmonic racetrack resonator with a trench structure. The depth of the structure and the length of the racetrack straightaways both significantly influence the characteristics of the plasmonic racetrack resonator. The optimu...
We demonstrated experimentally that an optical frequency signal can be detected through surface plasmon polaritons (SPPs) using an optical heterodyne technique. We fabricated an SPP detector consisting of a Au/Si Schottky diode with seven 10-μm-lo...

A novel plasmonic Raman sensor using periodic nano-hole and, potentially, nanofocusing arrays is investigated numerically and experimentally. The effect of structural parameters (such as periodicity of the structure, hole dimensions, etc.) is dete...
Light detection enhanced by surface plasmons was confirmed in Au film/n-type Si Schottky structures. Electrons excited directly with light in Au film overflowed into the n-type silicon, and this excitation was enhanced by surface plasmons induced ...
