Hybrid analysis of terahertz photoconductive antennas using energy balance transport model

A photoconductive antenna with tip-to-tip rectangular electrodes has been numerically investigated in the terahertz (THz) frequency band. Through a hybrid simulation employing an optoelectronic software, Silvaco, and a full-wave electromagnetic solver, CST, we will show that for analysis of photoconductive antennas in high power applications, energy balance transport model compared to the drift-diffusion model become more accurate due to the consideration of diffusion associated with the carriers temperature.
