Abstract

We report on intense, tunable, continuous, and coherent THz electromagnetic waves observed from differently shaped triangular mesas of the intrinsic Josephson junctions in single crystalline high-T_c superconducting Bi₂Sr₂CaCu₂O_8+δ. All samples are fabricated by focused ion beam milling.
