Plasmonic Slot Waveguide Propagation Analysis

Plasmonic slot waveguides provide extreme light confinement with the benefits of having naturally present electrodes for switching and high thermal conductivity metal layers to remove excess heat. Past works relied on numerical computation these structures, which is time-consuming lacks physical insight. Here, we an analytical model plasmonic determine modal properties based single-mode matching continuum. The accurate within 3% rigorous simulations. theory allows rapid design provides insight into mode propagation in information processing, optical manipulation, sensing applications.
