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…

Nanoscale displacement sensing based on nonlinear frequency mixing in quantum cascade lasers
F. P. Mezzapesa, L. L. Columbo, G. De Risi +4
We demonstrate a sensor scheme for nanoscale target displacement that relies on a single Quantum Cascade Laser (QCL) subject to optical feedback. The system combines the inherent s…
