GHz control of THz QCL band structure and gain by standing acoustic strain
Alexander S. Kuznetsov, Valentino Pistore, Lutz Schrottke +2
Active frequency comb generation and waveform control are central challenges in the terahertz (THz) domain. In THz quantum cascade lasers (QCLs), these functions have typically bee…
Sculpting harmonic comb states in terahertz quantum cascade lasers by controlled engineering
Elisa Riccardi, M. Alejandro Justo Guerrero, Valentino Pistore +6
Optical frequency combs (FCs), that establish a rigid phase-coherent link between the microwave and optical domains of the electromagnetic spectrum, are emerging as a key high-prec…
Ultrashort pulse generation from a graphene-coupled passively mode-locked terahertz laser
Elisa Riccardi, Valentino Pistore, Seonggil Kang +10
The generation of stable trains of ultra-short (fs-ps), terahertz (THz)-frequency radiation pulses, with large instantaneous intensities, is an underpinning requirement for the inv…
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…
Terahertz frequency combs exploiting an on-chip solution processed graphene-quantum cascade laser coupled-cavity architecture
F. P. Mezzapesa, K. Garrasi, J. Schmidt +11
The ability to engineer quantum-cascade-lasers (QCLs) with ultrabroad gain spectra and with a full compensation of the group velocity dispersion, at Terahertz (THz) frequencies, is…
