Abstract :
We experimentally demonstrate that utilizing plasmonic contact electrodes enhances the optical-to-terahertz conversion efficiency of photoconductive terahertz emitters and offers more than 50-times higher radiation powers compared to conventional photoconductive terahertz emission techniques without plasmonic electrodes.
