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. |
