Powerful terahertz emission from Bi2Sr2CaCu2O8+delta mesa arrays
T. M. Benseman, K. E. Gray, A. E. Koshelev +5
Stacks of intrinsic Josephson junctions (IJJs) in high-temperature superconductors enable the fabrication of compact sources of coherent terahertz radiation. Here we demonstrate th…

Tunable terahertz emission from Bi2Sr2CaCu2O8+δ mesa devices
T. M. Benseman, A. E. Koshelev, K. E. Gray +5
We have measured coherent terahertz emission spectra from Bi2Sr2CaCu2O8+δ mesa devices, as a function of temperature and mesa bias voltage. The emission frequency is found to be tu…

Emission of Terahertz Waves from Stacks of Intrinsic Josephson Junctions
K. E. Gray, L. Ozyuzer, A. E. Koshelev +8
By patterning mesoscopic crystals of Bi2Sr2CaCu2O8 (BSCCO) into electromagnetic resonators the oscillations of a large number of intrinsic Josephson junctions can be synchronized i…
