摘要
We demonstrate, both numerically and experimentally, adiabatic soliton spectral compression in a dispersionincreasing 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 30nm wavelength tuning ability is experimentally achieved. © 2011 Optical Society of America.
