Abstract

Supercontinuum (SC) properties are important in optical communication. The effects of pump power and wavelength on the generation dynamics of SC in dispersion shift fibers (DSF) were studied theoretically and experimentally. The results show that the SC generated in DSF is jointly induced by self-phase-modulation which broadens the entire response spectrum, by four-wave-mixing and by cross-phase-modulation, which boost the SC broadening. The SC band-width and flatness are related to the difference between the pump wavelength and the zero-dispersion wavelength. The SC spectrum has a 10 GHz repetition rate, an 80 nm bandwidth and a 3 dB flatness over a 20 nm spectral range. A two-optical fiber grating series increases the SC spectrum flatness by more than 8 dB.
