Welcome to the homepage of the research group on Nonlinear Dynamics, Nonlinear Optics and Lasers (DONLL).
Our reserach Group belongs to the Department of Physics of the Universitat Politècnica de Catalonia (UPC). We are located in Gaia research building, in the Campus of Terrassa (Rambla Sant Nebridi 22, Terrassa).
Our general goal is to study the nature, effects and, as far as possible, technological applications of nonlinear phenomena in the fields of photonics, complex systems and biophysics.
In the case of photonics, special emphasis is put on structured materials, in particular photonic crystals and gain/loss modultated media and lasers, as well as on semiconductor laser dynamics and ultra-short pulse interactions and diagnostics.
In the case of complex systems, we study complex networks (fundamentals and applications) and fracture dynamics in materials.
Finally, in the case of biophysics, attention is paid to neural excitability as well as to mesoscopic modelling of brain.
