Operating Vector Solitons with Chirped Sech Pulse Shapes

WebAn interesting question is whether soliton-like solutions exist near the zero-dispersion wavelength of an optical fiber. In the case of β 2 = 0, numerical solutions show [148] that a sech-shape pulse evolves over a length ξ ′ ∼ 10 / N ˜ 2 into a soliton that contains about half of the pulse energy. The remaining energy is carried by an ...
