Single-shot terahertz spectrometer using a microbolometer camera [PDF]
arXiv, 2020 We demonstrate a single-shot terahertz spectrometer consisting of a modified Mach-Zehnder interferometer and a microbolometer focal plane array. The spectrometer is simple to use and can measure terahertz field autocorrelations and spectral power with no moving parts and no ultrashort-pulsed laser.

Modeling DNA response to terahertz radiation [PDF]
Physical Review E, 2011 Collective response of DNA to terahertz electric fields is studied in a simple pair bond model. We confirm, with some caveats, a previous observation of destabilizing DNA breather modes and explore the parameter dependence of these modes. It is shown that breather modes are eliminated under reasonable physical conditions and that thermal effects are ...

Quantum-inspired terahertz spectroscopy with visible photons [PDF]
arXiv, 2020 Terahertz spectroscopy allows for identifying different isomers of materials, for drug discrimination as well as for detecting hazardous substances. As many dielectric materials used for packaging are transparent in the terahertz spectral range, substances might even be identified if packaged.

High-performing nonlinear visualization of terahertz radiation on a silicon charge-coupled device
Nature Communications, 2015 Photoinduced electron transitions can lead to significant changes of the macroscopic electronic properties in semiconductors. This principle is responsible for the detection of light with charge-coupled devices.

Stopping terahertz radiation without backscattering over a broad band.
Optics Express, 2015 We present an approach to completely stop terahertz radiation in an optical system with a gyroelectric semiconductor. This system is composed of guiding and stopping parts formed by the semiconductor with different cladding structures.

Spectral characteristics of terahertz radiation from plasmonic photomixers.
Optics Express, 2015 We present a comprehensive analysis of spectral characteristics of terahertz radiation from plasmonic photomixers. We fabricate plasmonic photomixer prototypes with plasmonic contact electrode gratings on a low temperature grown GaAs substrate and ...
