Time domain modeling: From nano-electronics to nano-photonics

We present a review of our work on time domain simulation of devices from nano-electronics to nano-photonics. Different equations and models are incorporated into Maxwell equations. Schrödinger equation is incorporated into Maxwell equations to model nano-electronics and nano-plasmonics devices, Lorentz-Drude (LD) dispersive model to simulate passive plasmonic devices, whereas a solid state model consisting of Pauli Exclusion principle, state filling effect and dynamic Fermi-Dirac Thermalization is incorporated to model active nano-photonics devices. LD and solid state models are hybridized for the simulation of active plasmonics devices. Graphics processing unit (GPU) is used to enhance the simulation speed, and as an example one of the models is implemented on it.
