Abstract :
In conclusion, we have demonstrated the generation of 1.18-2.10 μm ultra-widely broadened SC and 1.46-1.68 μm linearly chirped SC using only 5 m long two different kinds of highly nonlinear fibers and only 600 pJ pulse. This system is constructed with all the fiber devices and it is useful for practical application. The generated SC is experimentally analyzed using X-FROG technique. It is observed that the anti-Stokes pulse is overlapped with the trailing edge of the soliton pulse in PM-HN-DSF. It is considered that, after the a few meter propagation, the soliton pulses are redshifted due to the soliton self-frequency shift and the anti-Stokes components are gradually blueshifted due to the effect of pulse trapping by the soliton pulse in PM-HN-DSF.
