Quantum cascade laser roadmap

Carlo Silvestri, Aleksandar D. Rakić, 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…

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…

Phase analysis and full phase control of chip-scale infrared frequency combs

Luigi Consolino, Francesco Cappelli, Pablo Cancio +4

The road towards the realization of quantum cascade laser (QCL) frequency combs (QCL-combs) has undoubtedly attracted ubiquitous attention from the scientific community, as these d…

Retrieval of phase relation and emission profile of quantum cascade laser frequency combs

Francesco Cappelli, Luigi Consolino, Giulio Campo +12

The major development recently undergone by quantum cascade lasers has effectively extended frequency comb emission to longer-wavelength spectral regions, i.e. the mid and far infr…

Bow-Tie Cavity for Terahertz Radiation

Luigi Consolino, Annamaria Campa, Davide Mazzotti +3

We report on the development, testing, and performance analysis of a bow-tie resonant cavity for terahertz (THz) radiation, injected with a continuous-wave 2.55 THz quantum cascade…

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…
