Zhiwen Pan has done his Ph.D. in the fiber optics group in Leibniz Institute of Photonic Technology in Jena, Germany. He is currently a research associate
at the Otto Schott Institute of Materials Research, where he works on simulations in the Glass Chemistry Group II. His research interests focus on finite element simulations for
physical or engineering problems and molecule dynamic simulations for material science.

We will present a simulation study on the light scattering multimode fibres. With these results, the beam power in the fibre cores that leaks to the cladding and the environment
has been investigated. One aim of this work is to tailor the portion of light that transmitted out of the fibre along its length (e.g. homogeneously distributed). Such fibres have
potential applications as high efficient diffusive light sources for innovative decoration design , UV sources for photobioreactors  and IR sources for medical treatments .
Currently, most of the light scattering effects in optical fibres are induced by scatter centres inside. Our study proposes another mechanism for light scattering from optical fibres.
As will be shown later, the ability of our tailoring is more feasible as compared to the tailoring of the size, number density and distribution of the scattering centres in fibres.
Finally, a simulation of preparation of such fibres during fibre drawing process will also be presented.
