Extremely flat ultrawideband supercontinuum for WDM/TDM applications

We report an extremely flat (better than 3-dB), ultra-wide band (over 160-nm) supercontinuum source for use ni the C and L wavelength bands. The supercontinuum is generated using approximately 2.2 Km of commercially available single mode non-zero dispersion shifted fiber by exploiting soliton decomposition and Raman self-frequency shift nonlinear effects. A supercontinuum spectral flatness of better than 1-dB over a 115-nm wavelength range is achieved.
