Second harmonic generation and third harmonic generation in topological insulator-based van der Waals metamaterials
Alessandra Di Gaspare, Sara Ghayeb, Craig Knox +3
High-order harmonic generation (HHG) in solids - the frequency up-conversion of an optical signal - is governed by symmetries. At terahertz (THz) frequencies, HHG is a key technolo…
Improving terahertz-detection sensitivity of 8x8 FET arrays through liquid-nitrogen cooling in a compact low-noise cryostat
Jakob Holstein, Nicholas K. North, Arne Hof +10
We show that the sensitivity of antenna-coupled field-effect transistors (FETs) to terahertz (THz) radiation improves continuously with decreasing temperature. The noise-equivalent…
8x8 Patch-Antenna-Coupled TeraFET Detector Array for Terahertz Quantum-Cascade-Laser Applications
Jakob Holstein, Nicholas K. North, Michael D. Horbury +10
Monolithically integrated, antenna-coupled field-effect transistors (TeraFETs) are rapid and sensitive detectors for the terahertz range (0.3-10~THz) that can operate at room tempe…
Liquid-Crystal-Based Controllable Attenuators Operating in the 1-4 Terahertz Band
Aniela Dunn, Zhaopeng Zhang, Michael D. Horbury +12
Liquid-crystal devices (LCDs) offer a potential route toward adaptive optical components for use in the < 2 THz band of the electromagnetic spectrum. We demonstrate LCDs using a co…
Terahertz quantum cascade lasers with thin resonant-phonon depopulation active regions and surface-plasmon waveguides
M. Salih, P. Dean, A. Valavanis +5
We report three-well, resonant-phonon depopulation terahertz quantum cascade lasers with semi-insulating surface-plasmon waveguides and reduced active region (AR) thicknesses. Devi…
