摘要
1.25-1.95 mum widely broadened and almost flat super continuum is generated using only 5-m-long polarization maintaining highly nonlinear dispersion shifted fiber (PM-HN-DSF) and passively mode-locked Er-doped fiber laser. When the fiber length is 200 m, although there is a large depression around 1.5 mum, the optical spectra are widely broadened from 1.1 to 2.1 mum. The temporal distributions of the spectral components in the super continuum are observed using the technique of cross correlation frequency resolved optical gating, The initial generation process of the super continuum is directly observed.
