Sensitivity Enhancement in Si Nanophotonic Waveguides Used for Refractive Index Sensing

Sensitivity Enhancement in Si Nanophotonic Waveguides Used for Refractive Index Sensing

A comparative study is given for the sensitivity of several typical Si nanophotonic waveguides, including SOI (silicon-on-insulator) nanowires, nanoslot waveguides, suspended Si nanowires, and nanofibers. The cases for gas sensing (ncl ~ 1.0) and liquid sensing (ncl ~ 1.33) are considered. When usin...
