Abstract The light tracks in an anisotropic optical fiber are studied by the optical metric model. The ordinary and extraordinary light tracks are determined by solving the null geodesic equation. In the paraxial approximation the birefringence of the fiber is analyzed. The focusing and defocusing characte ristics of a light beam are described via the geodesic deviation equation

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.
