Terahertz surveys

Coherent two-dimensional terahertz-terahertz-Raman spectroscopy.

We present 2D terahertz-terahertz-Raman (2D TTR) spectroscopy, the first technique, to our knowledge, to interrogate a liquid with multiple pulses of terahertz (THz) light. This hybrid approach isolates nonlinear signatures in isotropic media, and is sensitive to the coupling and anharmonicity of thermally activated THz modes that play a central role in liquid-phase chemistry. Specifically, by ...

Terahertz Electronics

Applications of terahertz technology include detection of biological and chemical hazardous agents, explosive detection, applications in building and airport security, radio astronomy and space research, and in biology and medicine, for example, in cancer diagnostics. These applications have stimulated a lot of interest in terahertz electronics technologies that have potential to replace or aug...

Terahertz Technology

Terahertz technology applications, sensors, and sources are briefly reviewed. Emphasis is placed on the less familiar components, instruments, or subsystems. Science drivers, some historic background, and future trends are also discussed.

Terahertz plasmonics

Semiconductor microstructures can be used to tailor the dispersion properties of surface plasmon polaritons in the terahertz (THz) frequency range, and therefore can be used as important building blocks for terahertz optical devices. The physical principles of three structures are discussed: plasmonic second-order gratings, designer (spoof) surface plasmon polariton structures, and channel pola...
