Abstract: Au metallic nanorods are embedded in semiconductor microdisk in such a way that the whispering gallery mode of microdisk converts to dipole mode. For the simulation of Au nanorods, Lorentz-Drude (LD) model and for semiconductor microdisk, a solid state model is incorporated into Maxwell’s equations. The solid state model consists of Pauli Exclusion Principle, state filling and dynamical Fermi-Dirac thermalization effects. We study this dipole phenomenon for different materials, pumping current densities and field orientations.
