title: Wavelength-tunable spectral compression in a dispersion-increasing fiber.
abstract: 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.
