Abstract :
In this paper, a novel soliton compressor based on dispersion decreasing fiber (DDF) assistant by Raman gain is studied. The influence of Raman gain on compression quality is analyzed. The compressor is optimized by choosing proper gain. An optimization of the linear decreasing DDF compression method is made through distributed optical fiber Raman amplification with gain coefficient of 4.5dB/km. The pulse with width of 10ps is compressed down to 878.7fs, and the compression factor is 11.38. Our research results show that distributed Raman amplification in DDF not only increases the compression factor, but also improves the quality of compressed pulse.
