  dispersion flattened fiber
Besides the dispersion profile management, one of the key factors for stability is the maintenance of polarization in the dispersion-flattened fiber.
      


The femtosecond soliton propagation in the dispersion flattened fiber. Analytically and numerically is studied. The results show that Raman self frequency shift can make the dispersion flattened fiber have the same features as the dispersion decreasing fiber, and the shape and width of femtosecond soliton pulse can fundamentally remain unchanged over hundreds of dispersion length. It is possible that the femtosecond optical soliton communication links...

The femtosecond soliton propagation in the dispersion flattened fiber. Analytically and numerically is studied. The results show that Raman self frequency shift can make the dispersion flattened fiber have the same features as the dispersion decreasing fiber, and the shape and width of femtosecond soliton pulse can fundamentally remain unchanged over hundreds of dispersion length. It is possible that the femtosecond optical soliton communication links are made by use of dispersion flattened fiber and the lumped phase sensitive amplifiers.
