Abstract By using the perturhation theory and small-amplitude approximation with the self-induced Raman effect and the loss as well as gain of the fiber taken into account, the transmission properties of solitons in the nomal dispersion region near the zero-group-dispersion wavelength are analytically investigated in this paper. The result shows that not only the small-amplitude dark soliton but also the small-amplitude bright soliton may exist in the normal dispersion region near the zero-group-dispersion point. Their stabilities depend on the propagating direction and the region in which they are situated in the parameter-space. The conversion between bright and dark solitons may be realized by controlling the relative intensities of gain and loss along the fiber. This may be applied to the logic or arithmetic devices in the integrated optical circuit.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
