Ultrashort Pulse Dynamics

The nonlinear propagation of light in media has been a topic of research since the 1980s through the numerical simulation of the non-linear Schrödinger equation (NLSE). On the other hand, thanks to the development of photonic crystal fibers (PCFs), ultra-short pulseshave become a commonplace in optics labs, these pulses contain only few optical cycles and therefore its theoretical and numerical modeling is still a challenge due to highly nonlinear effects present in them, causing effects such as: soliton pulse formationoptical four-wave mixing and supercontinuum generation.
