Abstract

The THz radiation emitted from rectangular mesas of single-crystal Bi2Sr2CaCu2O8+delta was studied using angular distribution measurements and Fourier transform infrared spectroscopy. Unlike the recent theoretical predictions, the results provide strong, evidence for a dual-source mechanism in which the uniform and non-uniform parts of the ac-Josephson Current act as electric and magnetic Current Sources, respectively. The latter synchronizes with cavity modes of the mesa with integral harmonics of the fundamental radiation.
