A 3.5-THz, x6-Harmonic, Single-Ended Schottky Diode Mixer for Frequency Stabilization of Quantum-Cascade Lasers
Divya Jayasankar, Vladimir Drakinskiy, Nick Rothbart +8
Efficient and compact frequency converters are essential for frequency stabilization of terahertz sources. In this paper, we present a 3.5-THz, x6-harmonic, integrated Schottky dio…
Evaluation of Low-Cost Thermal Laser Stimulation for Data Extraction and Key Readout
Thilo Krachenfels, Heiko Lohrke, Jean-Pierre Seifert +3
Recent attacks using thermal laser stimulation (TLS) have shown that it is possible to extract cryptographic keys from the battery-backed memory on state-of-the-art field-programma…
Electron energy relaxation in disordered superconducting NbN films
Mariia Sidorova, Alexej Semenov, Heinz-Wilhelm Hübers +8
We report on the inelastic-scattering rate of electrons on phonons and relaxation of electron energy studied by means of magnetoconductance, and photoresponse, respectively, in a s…
Terahertz dynamic aperture imaging at stand-off distances using a Compressed Sensing protocol
Sven Augustin, Peter Jung, Sven Frohmann +1
In this text, results of a 0.35 terahertz (THz) dynamic aperture imaging approach are presented. The experiments use an optical modulation approach and a single pixel detector at a…
The upGREAT dual frequency heterodyne arrays for SOFIA
C. Risacher, R. Güsten, J. Stutzk +30
We present the performance of the upGREAT heterodyne array receivers on the SOFIA telescope after several years of operations. This instrument is a multi-pixel high resolution (R >…
Mask Responses for Single-Pixel Terahertz Imaging
Sven Augustin, Sven Frohmann, Peter Jung +1
Terahertz (THz) radiation meaning electromagnetic radiation in the range from 0.1 THz (3 mm) to 10 THz (30 mu) has the unique advantage of easily penetrating many obstructions whil…
