Abstract

An effective simulation and design platform is presented in this paper for semiconductor plasmonic nanodisk laser. The three-dimensional laser structure is modeled and simulated with a body-of-revolution finite-difference-timedomain (BOR-FDTD) combined with the multi-level gain medium model and the Drude-Lorentz metal model, which gives a comprehensive spatial and temporal electromagnetic simulation of the nano-cavity and its lasing performance above the threshold. A semiconductor plasmonic nano-disk laser embedded in silver film is designed and the spatial and temporal lasing performance is numerically demonstrated. The physical volume of the nanodisk laser is only 1.17 (λ/2n)³ (a diameter of 200 nm and a height of 300 nm) and it has lasing wavelength at 1400 nm with a pumping threshold of 0.4 μW.
