Parabolic pulse generation at 1550 nm via Raman amplification in standard telecommunications grade dispersion shifted fiber

In this paper, numerical simulations demonstrate that parabolic pulse generation can also be observed in Raman amplifiers using standard telecommunications-grade dispersion shifted fibre (DSF) and, in particular, that this can be achieved using input pulses from inexpensive gain-switched semiconductor laser sources. The semiconductor laser based Raman parabolic pulse amplifiers finds wide application in the development of compact and environmentally-stable ultrafast sources around 1550 nm.
