  • Abstract
    We present an efficient photoconductive terahertz emitter based on a logarithmic spiral antenna array that incorporates plasmonic contact electrodes on a LT-GaAs substrate. Under a 400 mW optical pump power, the emitter generates 1.9 mW of terahertz radiation in the 0.1 - 2 THz range.
