A comparison of the performance of THz photoconductive antennas Moreno, Enrique Fernández Pantoja, Mario Alberto Rubio Bretones, Amelia Consuelo Ruiz Cabello, Miguel González García, Salvador Photoconductive antennas Terahertz technology This letter explores the influence of the geometry of bias electrodes in the performance of terahertz (THz) photoconductive antennas (PCAs). To this end, a methodology is presented to calculate numerically the operational bandwidth and radiation efficiency of the PCAs. The procedure is validated through a comparison to experimental measurements. Also, results are depicted from numerical simulations of different PCAs under varying conditions of bias voltage, doping factor, and incident optical power. It is concluded that an appropriate con figuration of the electrodes may double the efficiency of the antennas, with a penalty in the bandwidth of the radiated pulse usually smaller than 10%. 2018-04-10T10:01:56Z 2018-04-10T10:01:56Z 2014 journal article Moreno, Enrique; et. al.
