Abstract

The THz radiation emitted from rectangular mesas of single-crystal Bi 2Sr2CaCu2O8+δ 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. © 2010 The Physical Society of Japan.
