Paper Abstract

We report on the application of a photoconductive (PC) frozen wave generator (FWG) for the generation of two-cycle THz radiation. A bipolar PC array comprised of four electrodes is employed in the production of THz electrical transients. Variations in the uniformity of the optical excitation intensity across the FWG PC gaps are found to provide a means of controlling the temporal chirp and power spectral bandwidth of the resulting electrical signals. Upon generating the electrical transients, the signals are launched, and later received, with integrated dipole antennas.
