Impact of initial pulse shape on the nonlinear spectral compression in optical fibre

Boscolo, Sonia, Chaussard, Frederic, Andresen, Esben, Rigneault, Hervé and Finot, Christophe (2017). Impact of initial pulse shape on the nonlinear spectral compression in optical fibre. Optics and Laser Technology, Early , pp. 301-309.


We theoretically study the effects of the temporal intensity profile of the initial pulse on the nonlinear propagation spectral compression process arising from nonlinear propagation in an optical fibre. Various linearly chirped input pulse profiles are considered, and their dynamics is explained with the aid of time-frequency representations. While initially parabolic-shaped pulses show enhanced spectral compression compared to Gaussian pulses, no significant spectral narrowing occurs when initially super-Gaussian pulses are used. Triangular pulses lead to a spectral interference phenomenon similar to the Fresnel bi-prism experiment.
