Current compact emitter and receiver technologies are generally inefficient and impractical
at terahertz (THz) frequencies between 0.1 and 10 THz. Hence, a gap exists between …

Diode is one of the basic electronic components. It has a nonreciprocal current response,
associated with a broken space/time reversal symmetry. Here we demonstrate prototypes of …

Current-biased Josephson junctions can act as detectors of electromagnetic radiation. At
optimal conditions, their sensitivity is limited by fluctuations causing stochastic switching …

Sensing systems that can ensure product reliability in a broad range of environments are
urgently required for broader application of the internet of things. Imaging technologies …

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

Advanced microwave technologies constitute the foundation of a wide range of modern
sciences, including microwave integrated circuits, quantum computing, microwave …

Communication using terahertz (∼ 1012 Hz) electromagnetic waves is critical for
developing sixth-generation wireless network infrastructures. Conflictions between stable …

Low power efficiency is one of the main problems of terahertz (THz) sources, colloquially
known as “the THz gap.” In this work we present prototypes of THz devices based on …

A compact cryogenic terahertz emitter is highly desired for applications in terahertz
astronomy with a broad frequency range of emissions and relatively high emission power. In …

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 …
