Here we studied various combinations (two symmetric and two asymmetric designs) of stripline widths for stripline photoconductive emitters fabricated on semi-insulating GaAs. We found out that the THz emission efficiency depends strongly on the anode width. The wider the anode, the higher is the THz amplitude. Cathode width does not play a significant role in THz emission performance.
