Ultrabroadband THz/IR upconversion and photovoltaic response in semi-conductor ratchet based upconverter
Peng Bai, Ning Yang1, Weidong Chu +12
An ultrabroadband upconversion device is demonstrated by direct tandem integration of a p-type GaAs/AlxGa1-xAs ratchet photodetector (RP) with a GaAs double heterojunction LED (DH-…
Realization of ultrabroadband THz/IR photoresponse in a bias-tunable ratchet photodetector
Peng Bai, Xiaohong Li, Ning Yang +14
High performance Terahertz (THz) photodetector has drawn wide attention and got great improvement due to its significant application in biomedical, astrophysics, nondestructive ins…
High temperature metamaterial terahertz quantum detector
Mathieu Jeannin, Thomas Bonazzi, Djamal Gacemi +7
We demonstrate a high temperature performance quantum detector of Terahertz (THz) radiation based on three-dimensional metamaterial. The metamaterial unit cell consists of an induc…
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…
Long-wavelength infrared photovoltaic heterodyne receivers using patch-antenna quantum cascade detectors
Azzurra Bigioli, Giovanni Armaroli, Angela Vasanelli +7
Quantum cascade detectors (QCD) are unipolar infrared devices where the transport of the photo excited carriers takes place through confined electronic states, without an applied b…
