Prof. Masoller’s research line on nonlinear dynamics
of semiconductor lasers
|
Semiconductor lasers are important practical
devices, widely used in datacom, telecom, biomedical applications (imaging,
sensors), etc. While “solitary” lasers emit a stable output, under external
perturbations semiconductor lasers display a variety of nonlinear behaviors.
The research in our lab aims to advance the understanding of nonlinear
phenomena and exploit them for innovative applications. |
