Continuous and coherent terahertz radiation is emitted from mesa-shaped devices made of the intrinsic Josephson junctions (IJJs) of high-T c superconductor $Bi_{2}Sr_{2}CaCu_{2}O_{8+\delta }$. We have succeeded in separating the functions of resonato

Since the discovery of continuous, coherent THz radiation from intrinsic Josephson junctions (IJJs) constructed in the single crystals of Bi 2 Sr 2 CaCu 2 O 8+δ in 2007, various types of device structures have been developed. Thermal management of J
