Effect of stripline electrodes on coherent terahertz emission from BSCCO intrinsic Josephson junctions

ORAL

Abstract

Since terahertz radiation in the 0.3--10 THz frequency range is technologically attractive, terahertz generation from stacks of intrinsic Josephson junctions in Bi$_{\mathrm{2}}$Sr$_{\mathrm{2}}$CaCu$_{\mathrm{2}}$O$_{\mathrm{8+\delta }}$ (Bi-2212) has become a major focus of both experimental and theoretical research [U. Welp \textit{et al.}, Nat. Photonics \textbf{7}, 702 (2013)] In the present study, we investigate the effect of a stripline electrode on the coherent terahertz emission from Bi-2212 intrinsic junctions. We observed peculiar emission patterns with temperature-independent stripes in the current-voltage characteristics. We analyzed the experimental data using an electromagnetic simulator to investigate the impedance matching conditions for efficient terahertz emission from Bi-2212 mesas.
