Nozaki-Bekki optical solitons
Nikola Opačak, Dmitry Kazakov, Lorenzo L. Columbo +8
Recent years witnessed rapid progress of chip-scale integrated optical frequency comb sources. Among them, two classes are particularly significant -- semiconductor Fabry-Perót las…
Roadmap on multimode light shaping
Marco Piccardo, Vincent Ginis, Andrew Forbes +35
Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously com…
Unifying frequency combs in active and passive cavities: Temporal solitons in externally-driven ring lasers
L. Columbo, M. Piccardo, F. Prati +8
Frequency combs have become a prominent research area in optics. Of particular interest as integrated comb technology are chip-scale sources, such as semiconductor lasers and micro…
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 induced by collisions in a forced semiconductor laser
Pierre Walczak, Cristina Rimoldi, Francois Gustave +5
We report on the experimental study of an optically driven multimode semiconductor laser with 1~m cavity length. We observed a spatiotemporal regime where real time measurements re…
Extrinsic electromagnetic chirality in all-photodesigned one-dimensional THz metamaterials
Carlo Rizza, Lorenzo Columbo, Massimo Brambilla +2
We suggest that all-photodesigned metamaterials, sub-wavelength custom patterns of photo-excited carriers on a semiconductor, can display an exotic extrinsic electromagnetic chiral…
