Supercontinuum generation in a single-mode optical fiber with novel dispersion profile. (English) Zbl 1170.78392

J. Mod. Opt. 56, No. 4, 477-481 (2009).
Summary: A novel dispersion model different from the conventional one is introduced to enhance supercontinuum generation in dispersion-flattened/decreasing fiber. The results show that supercontinuum spectrum generated in this fiber is by far wider than that in the conventional one,whose flat width can be nearly 1000 nm. The results further show that both the fiber parameters such as peak chromatic dispersion, dispersion differential constant and dispersion decreasing coefficient and the pump pulse parameters including pulse width, soliton order, frequency chirp are crucial to the flat ultra-wideband supercontinuum spectrum generated in this fiber.
