A temporal and spatial simulation and design of nanoplasmonic laser based on a semiconductor nanodisk is presented in this paper. A body-of-revolution finite-difference-time-domain (BOR-FDTD) simulation incorporated with a semiclassical multilevel model for the semiconductor gain medium and Drude-Lorentz model for the metal is developed for an efficient simulation of disk/ring plasmonic laser. A nanodisk semiconductor-plasmonic laser with a radius of 35 nm is designed, and the spatial and temporal lasing performance is demonstrated numerically.
