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…

Mixing properties of room temperature patch-antenna receivers in a mid-infrared (9um) heterodyne system
A. Bigioli, D. Gacemi, D. Palaferri +10
A room-temperature mid-infrared (9 um) heterodyne system based on high-performance unipolar optoelectronic devices is presented. The local oscillator (LO) is a quantum cascade lase…
