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…
Frequency and intensity noise of a grating-tuned external-cavity quantum cascade laser
Irene La Penna, Tecla Gabbrielli, Cristina Rimoldi +6
Quantum cascade lasers (QCLs) are semiconductor-heterostructure devices known for their emission in the mid-infrared and THz spectral regions. Due to their operating regime, their…
Bridging mid and near infrared by combining optomechanics and self mixing
Tecla Gabbrielli, Chenghong Zhang, Francesco Cappelli +8

A novel study on harmonic frequency combs emitted by Quantum Cascade Lasers (QCLs) is here presented, demonstrating the presence of intensity correlations between twin modes charac…
Observing the intrinsic linewidth of a quantum-cascade laser: beyond the Schawlow-Townes limit
S. Bartalini, S. Borri, P. Cancio +6
A comprehensive investigation of the frequency-noise spectral density of a free-running mid-infrared quantum-cascade laser is presented for the first time. It provides direct evide…
Saturated-absorption cavity ring-down spectroscopy
G. Giusfredi, S. Bartalini, S. Borri +4
We report on a novel approach to cavity-ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows to decouple and simultaneously retrieve emp…
