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…
Room temperature 9 m photodetectors and GHz heterodyne receivers
Daniele Palaferri, Yanko Todorov, Azzurra Bigioli +11
Room temperature operation is mandatory for any optoelectronics technology which aims to provide low-cost compact systems for widespread applications. In recent years, an important…
