Bridging the terahertz-gap using high-Tc superconducting emitters with coherent and continuous electromagnetic wave (EMW) radiation

摘要

Operating high-Tc superconducting intrinsic Josephson junction emitters at 77 K, coherent and continuous THz EMWs with an intensity of several tens of μW can be generated, which provides us with sufficient power for the simple imaging operation. The frequency range may be extended widely as high as 2.4 THz from 0.4 THz. An example is given.
