On-chip, self-detected THz dual-comb spectrometer
Markus Rösch, Giacomo Scalari, Gustavo Villares +3
We present a directly generated on-chip dual-comb source at THz frequencies. The multi-heterodyne beating signal of two free-running THz quantum cascade laser frequency combs is me…
On-chip Dual-comb based on Quantum Cascade Laser Frequency Combs
Gustavo Villares, Johanna Wolf, Dmitry Kazakov +4
Dual-comb spectroscopy is emerging as one of the most appealing applications of mid-infrared frequency combs for high-resolution molecular spectroscopy, as it leverages on the uniq…
Quantum Cascade Laser Frequency Combs
Jérôme Faist, Gustavo Villares, Giacomo Scalari +4
It was recently demonstrated that broadband quantum cascade lasers can operate as frequency combs. As such, they operate under direct electrical pumping at both mid-infrared and TH…
Dispersion engineering of Quantum Cascade Lasers frequency combs
Gustavo Villares, Sabine Riedi, Johanna Wolf +4
Quantum cascade lasers are compact sources capable of generating frequency combs. Yet key characteristics - such as optical bandwidth and power-per-mode distribution - have to be i…
Intrinsic linewidth of quantum cascade laser frequency combs
Francesco Cappelli, Gustavo Villares, Sabine Riedi +1
The frequency noise power spectral density of a free-running quantum cascade laser frequency comb is investigated. A plateau is observed at high frequencies, attributed to the quan…
