Detection & Diagnostic Systems


 

The Detection & Diagnostic Systems Department conducts research and development related to instruments and non-destructive evaluation (NDE) techniques for characterization of materials and determination of system parameters related to different energy systems (including fossil, transportation, and nuclear). The Department also develops sensors and technologies for non-energy-producing applications such as homeland security and biomedical engineering.

Emission of Coherent THz Radiation from Superconductors by L. Ozyuzer, A. E. Koshelev, C. Kurter, N. Gopalsami, Q. Li, M. Tachiki, K. Kadowaki, T. Yamamoto, H. Minami, H. Yamaguchi, T. Tachiki, K. E. Gray, W.-K. Kwok, U. Welp
Compact solid-state sources of terahertz (THz) radiation are being sought for sensing, imaging, and spectroscopy applications across the physical and biological sciences. We demonstrate that coherent continuous-wave THz radiation of sizable power can be extracted from intrinsic Josephson junctions in the layered high-temperature superconductor Bi2Sr2CaCu2O8. In analogy to a laser cavity, the excitation of an electromagnetic cavity resonance inside the sample generates a macroscopic coherent state in which a large number of junctions are synchronized to oscillate in phase. The emission power is found to increase as the square of the number of junctions reaching values of 0.5 microwatt at frequencies up to 0.85 THz, and persists up to ~50 kelvin. These results should stimulate the development of superconducting compact sources of THz radiation... ~~ Excerpt from Science Magazine, Vol. 318, 23 Nov. 2007
