Abstract
We study here the effect of the electrode parameters on the terahertz emission efficiency of large-area emitters based on interdigitated electrodes. Electrode parameters are optimized to get maximum terahertz emission by optimizing the balance condition among the emission efficiency of individual electrode pairs, number of emitters per unit area, and fraction of semiconductor exposed for optical pumping. A maximum enhancement by about 50 % in the peak to peak electric field is observed as compared to the previous state of the art design.
Keywords: Terahertz emitters; photoconductive switch; interdigitated electrode
