A novel adiabatic pulse compression scheme using silica-based functional fibers with enhanced nonlinearity

In this paper, a novel scheme for adiabatic pulse compression using silica-based functional fibers with enhanced nonlinearity is proposed and investigated in detail. The numerical results show that the pulse compression in this kind of fiber satisfies the adiabatic condition by selecting the reasonable systematic parameters. Although the higher order nonlinear effects, especially the Raman self-frequency-shift, are obvious due to the increased gradually nonlinearity, high quality compressed pulse can also be obtained except generating an extra-time-delay according to retarded frame.
