Chip-scale terahertz frequency combs through integrated intersubband polariton bleaching
Francesco P. Mezzapesa, Leonardo Viti, Lianhe Li +5
Quantum cascade lasers (QCLs) represent a fascinating accomplishment of quantum engineering and enable the direct generation of terahertz (THz) frequency radiation from an electric…
Homogeneous quantum cascade lasers operating as Terahertz frequency combs over their entire operational regime
Alessandra Di Gaspare, Leonardo Viti, Harvey E. Beere +2
We report a homogeneous quantum cascade laser (QCL) emitting at Terahertz (THz) frequencies, with a total spectral emission of about 0.6 THz centered around 3.3 THz, a current dens…
Quantum Cascade Laser Based Hybrid Dual Comb Spectrometer
Luigi Consolino, Malik Nafa, Michele De Regis +9
Four-wave-mixing-based quantum cascade laser frequency combs (QCL-FC) are a powerful photonic tool, driving a recent revolution in major molecular fingerprint regions, i.e. mid- an…
Ultrafast two-dimensional field spectroscopy of terahertz intersubband saturable absorbers
Jürgen Raab, Christoph Lange, Jessica L. Boland +9
Intersubband (ISB) transitions in semiconductor multi-quantum well (MQW) structures are promising candidates for the development of saturable absorbers at terahertz (THz) frequenci…
Bow-Tie Cavity for Terahertz Radiation
Luigi Consolino, Annamaria Campa, Davide Mazzotti +3
We report on the development, testing, and performance analysis of a bow-tie resonant cavity for terahertz (THz) radiation, injected with a continuous-wave 2.55 THz quantum cascade…
Phase-sensitive terahertz imaging using room-temperature near-field nanodetectors
Maria C. Giordano, Leonardo Viti, Oleg Mitrofanov +1
Imaging applications in the terahertz (THz) frequency range are severely restricted by diffraction. Near-field scanning probe microscopy is commonly employed to enable mapping of t…
