Influence of the pumping configuration on the generation of optical similaritons in optical fibers
نویسندگان
چکیده
The impact of forward and backward amplification schemes on the generation of optical similaritons has been numerically and experimentally investigated around 1550 nm using a fiber based Raman amplifier. The pumping configuration does not affect the similariton nature of the output pulse, but it significantly influences the characteristics of the pulse. Shorter and higher peak-power similaritons are obtained using a backward pumping scheme. The study of the influence of the initial pulse energy also highlights the higher pumping efficiency obtained in the case of counterpropagating amplification. keywords : nonlinear fiber optics, ultrashort pulse amplification, parabolic pulses, amplification schemes
