Author Affiliations +
In this paper, we present simulation results pertaining to our broadband solid-state optically and electrically pumped THz source design. Our design consists of a thin layer of dielectric sandwiched between a nano-grating and a thin film, such as metal, semiconductor, or high electron mobility material. By passing a DC current through the lower layer, a THz emission will be radiated from the nano-grating. We demonstrate preliminary current injection effects on surface plasmons propagating on this device utilizing known analytical surface plasmon formulas and COMSOL Multiphysics finite element analysis software.
