Nanoscale displacement sensing based on nonlinear frequency mixing in quantum cascade lasers
F. P. Mezzapesa, L. L. Columbo, G. De Risi +4
We demonstrate a sensor scheme for nanoscale target displacement that relies on a single Quantum Cascade Laser (QCL) subject to optical feedback. The system combines the inherent s…

Cavity Light Bullets: 3D Localized Structures in a Nonlinear Optical Resonator
Massimo Brambilla, Lorenzo Columbo, Tommaso Maggipinto
We consider the paraxial model for a nonlinear resonator with a saturable absorber beyond the mean-field limit and develop a method to study the modulational instabilities leading…
