Coherent multi-mode dynamics in a Quantum Cascade Laser: Amplitude and Frequency-modulated Optical Frequency Combs
Carlo Silvestri, Lorenzo Luigi Columbo, Massimo Brambilla +1
We cast a theoretical model based on Effective Semiconductor Maxwell-Bloch Equations and study the dynamics of a multi-mode mid-Infrared Quantum Cascade Laser in Fabry Perot with t…
Extreme events in forced oscillatory media in 0, 1 and 2 dimensions
S. Barland, M. Brambilla, L. Columbo +14
One of the open questions in the field of optical rogue waves is the relevance of the number of spatial dimensions in which waves propagate. Here we review recent results on extrem…
Self-pulsing in single section ring lasers based on Quantum Dot materials: theory and simulations
Lorenzo Luigi Columbo, Paolo Bardella, Mariangela Gioannini
We studied theoretically coherent phenomena in the multimode dynamics of single section semiconductor ring lasers with Quantum Dots (QDs) active region. In the unidirectional ring…
Self-generation of optical frequency comb in single section Quantum Dot Fabry-Perot lasers: a theoretical study
Paolo Bardella, Lorenzo Luigi Columbo, Mariangela Gioannini
Optical Frequency Comb (OFC) generated by semiconductor lasers are currently widely used in the extremely timely field of high capacity optical interconnects and high precision spe…
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…
