  • Abstract
    Using plasmonic gratings, we have greatly increased the photo-absorbing active area of a photoconductive terahertz emitter, without sacrificing device ultrafast operation. More than 20 times radiation power enhancement was measured when compared to a similar emitter without plasmonic gratings.
