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…
Tunable, grating-gated, graphene-on-polyimide terahertz modulators
Alessandra Di Gaspare, Eva A. A. Pogna, Luca Salemi +10
We present an electrically switchable graphene terahertz (THz) modulator with a tunable-by-design optical bandwidth and we exploit it to compensate the cavity dispersion of a quant…
High dynamic range, heterogeneous, terahertz quantum cascade lasers featuring thermally-tunable frequency comb operation over a broad current range
Katia Garrasi, Francesco P. Mezzapesa, Luca Salemi +7
We report on the engineering of broadband quantum cascade lasers (QCLs) emitting at Terahertz (THz) frequencies, which exploit a heterogeneous active region scheme and have a curre…
