Abstract :
To realize extremely wideband wavelength-tunable femtosecond (fs) pulse generation, we propose a dispersion-flattened comblike profiled fiber that is a pulse compressor comprised of low dispersion-slope highly nonlinear fiber and zero dispersion-slope nonzero dispersion-shifted fiber (ZDS-NZDSF). We also apply ZDS-NZDSF to a soliton converter to reshape and compress a seed pulse train generated from a tunable laser source and an intensity modulator. Using the proposed scheme, we successfully generate 100-fs optical pulse from the seed pulse with the varied wavelengths of 1530, 1570, and 1610 nm
