Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. RakiÄ, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…
Sub-doppler trace-gas photoacoustic spectroscopy
Jacopo Pelini, Stefano Dello Russo, Chenghong Zhang +10
Molecules are emerging as new benchmark for metrology and fundamental physics research, driving the demand for spectroscopic techniques combining high sensitivity and resolution. P…
Electron-to-photon noise transfer in mid-infrared semiconductor lasers
Irene La Penna, Tecla Gabbrielli, Borislav Hinkov +8
Noise characteristics of state-of-the art light sources are crucial parameters in understanding their limitations towards quantum applications. This work describes a method to stud…
Self-mixing-based photoacoustic sensing
Tecla Gabbrielli, Jacopo Pelini, Chenhong Zhang +7
Versatile, ultracompact, easy-to-handle, high-sensitivity sensors are compelling tools for in situ pivotal applications, such as medical diagnostics, security and safety assessment…
Near-single-photon atto-watt detection at mid-infrared wavelengths by a room-temperature balanced heterodyne set-up
Daniele Palaferri, Lorenzo Mancini, Chiara Vecchi +8
Single photon detection is the underpinning technology for quantum communication and quantum sensing applications. At visible and near-infrared wavelengths, single-photon-detectors…
