We demonstrate, both numerically and experimentally, adiabatic soliton spectral compression in a dispersion-increasing fiber (DIF). We show that a positively chirped pulse provides better spectral compression in a DIF with a large anomalous dispersion ramp. An experimental spectral compression ratio of 15.5 is obtained using 350 fs positively chirped input pulse centered at 1.5 μm. A 30 nm wavelength tuning ability is experimentally achieved.

Large-scale and structure-tunable laser spectral compression in an optical dispersion-increasing fiber.

Spectrally compressed spectrum with two bright peaks is demonstrated for the first time, to the authors' knowledge, and the structure of the dual-peaked compressed spectra is adjustable through the interplay of initial pulse chirp and energy.
