Electromagnetic radiation at frequencies in the terahertz (THz) range is highly interesting for
potential applications in biology or medical diagnostics, high-bandwidth communication …

Most of superconductors in a magnetic field are penetrated by a lattice of quantized flux
vortices. In the presence of a transport current causing the vortices to cross sample edges …

Suitably patterned single crystals made of the cuprate superconductor Bi 2 Sr 2 CaCu 2 O
8+ x (BSCCO), intrinsically forming a stack of Josephson junctions, can generate …

Mesa-shaped structures of the high critical temperature (high-T c) superconductor Bi 2 Sr 2
Ca Cu 2 O 8+ δ contain stacked intrinsic Josephson junctions. As such, they are a promising …

We report on spectrometric gas detection using terahertz waves radiated from Bi 2 Sr 2
CaCu 2 O 8+ δ (BSCCO) intrinsic Josephson-junction stacks. The emission frequency is …

Using our recent design of thermally managed sandwich device structures, we studied the
radiation frequency characteristics of three such devices of the same rectangular …

We examine coupling interactions used to synchronize macroscopic Josephson oscillations
induced in intrinsic Josephson-junction (IJJ) mesa stacks made of a Bi 2212 single crystal …

We demonstrate mutual synchronization of Josephson oscillations in multiple stacks of
intrinsic Josephson junctions of the cuprate superconductor Bi 2 Sr 2 Ca Cu 2 O 8+ δ …

Using low-temperature scanning laser microscopy (LTSLM), we have studied the cavity
resonance behavior of a rectangular B i 2 S r 2 CaC u 2 O 8+ δ mesa THz device containing …

Polarized terahertz (THz) sources are important components in THz technologies. This
paper highlights and discusses recent progress and measurement methods in the …
