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 rich variety of nonlinear
behaviors. The aim of the experimental and numerical work done in our lab is
to advance the understanding of nonlinear phenomena induced by optical
feedback and current modulation. |
