Comb-like profiled fibre for efficient generation of high quality 160 GHz sub-picosecond soliton train

A comb-like profiled fibre (CPF), an alternate concatenation of a dispersive fibre and nonlinear fibre, is capable of emulating an arbitrary dispersion profile over distance for high quality optical pulse compression. It is demonstrated experimentally that CPF is efficient for the reshaping of an optical beat signal into a high quality 160 GHz 730 fs soliton pulse train with remarkably low noise, while stimulated Brillouin scattering was well suppressed.
