Effective pulse compression in dispersion decreasing and nonlinearity increasing fibers

We numerically demonstrate effective pulse compression in photonic crystal fibers with linearly decreasing dispersion and linearly increasing nonlinearity. The proposed fiber design can achieve nearly chirp-free and pedestal-free pulse compression and provides a feasible and a much simpler design in practice. (C) 2014 Elsevier B.V.
