Terahertz source-on-a-chip with decade-long stability using layered superconductor elliptical microcavities
Mingqi Zhang, Shungo Nakagawa, Yuki Enomoto +8
Coherent, continuous-wave, and electrically tunable chip-scale terahertz (THz) sources are critical for emerging applications in sensing, imaging, spectroscopy, communication, spac…
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…
Direct imaging of hot spots in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} mesa terahertz sources
T. M. Benseman, A. E. Koshelev, W. -K. Kwok +5
Stacks of intrinsic Josephson junctions (IJJs) made from high-temperature superconductors such as Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} (Bi-2212) are a promising source of coherent continuou…
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…
Fluctuating pancake vortices revealed by dissipation of Josephson vortex lattice
A. E. Koshelev, A. I. Buzdin, I. Kakeya +2
In strongly anisotropic layered superconductors in tilted magnetic fields the Josephson vortex lattice coexists with the lattice of pancake vortices. Due to the interaction between…
Thermal Management in Large Bi2212 Mesas used for Terahertz Sources
C. Kurter, K. E. Gray, J. F. Zasadzinski +8
We present a thermal analysis of a patterned mesa on a Bi2Sr2CaCu2O8 (Bi2212) single crystal that is based on tunneling characteristics of the c-axis stack of ~800 intrinsic Joseph…
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…
