Multiphysics modeling of plasmonic nanodevices

Plasmonic devices are modeled and simulated by incorporating a Lorentz-Drude model for the metallic materials and a multi-level multi-electron quantum model for the semiconductor materials into Maxwell´s equations. Some novel plasmonic devices such as a detector consisting of a dipole nanoantenna and a metal-semiconductor-metal detector, and a ring resonator based on a hybrid dielectric loaded waveguide are investigated with developed multiphysics modeling method. Simulation results show that the devices are very promising and can be combined with nanoelectronic integrated circuits to further improve their performance.
