Nonlinear pulse reshaping in passive optical fibers towards quasi-parabolic waveforms

Abstract

Generation and applications of the optical pulses with a parabolic intensity profile has developed into the area of dynamic research activity over recent years. Parabolic pulses can propagate remaining their parabolic profile. Particularly these pulses resist to the deleterious effect of the optical wave breaking. They are of great interest for a number of applications including the high power pulse generation, and all optical signal processing. Alternative methods of generating parabolic pulses are of especial interest in the context of non-amplification usage, such as optical telecommunications. It is found that Gaussian waveforms provide best quasi-parabolic pulses among others and within shortest distance. There is a range of soliton numbers where the shape of quasi-parabolic pulse is closest to parabolic one.
