Abstract

Electrodes have an important influence on the terahertz (THz) radiation efficiency of photoconductive antenna, especially photoconductive antennas combined with nanostructures. The nanostructured photoconductive antennas with rectangular electrodes, traditional electrodes and bow-tie electrodes were simulated by the finite difference time domain method. The simulation results show that the bow-tie electrode is better than the rectangular electrode and the traditional electrode. The research results provide a promising scheme for selecting the appropriate electrode structure of the nanostructured photoconductive antenna.
