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 ... Webphase can describe the pulse behavior satisfactorily. If they do, the theoretical description of pulse propagation and interaction with matter can be greatly simpli-ﬁed by applying the slowly varying envelope approximation (SVEA), as will be evident later in this chapter.
