Keywords:silicon photonics, sensor, plasmonics

Structural optimization of plasmonic slot waveguide sensors with circular cavities in symmetric and serial configuration is investigated. High-performances are theoretically demonstrated with large extinction ratio of 68.8 dB and extremely high sensitivity of 1155 nm/RIU.
