The fibre is especially designed for indirect illumination applications and the special shape of the filament cross‐section permits the formation of a distinct asymmetric radiation pattern. These fibres can focus the radially emitted light on particular locations, e.g. in order to cure resins or polymers at well‐defined positions, or may be used as indirect illumination sources in car interiors. The polymer material is commercial optical‐grade poly(methyl methacrylate) (PMMA) that is compounded with different concentrations of a TiO<jats:sub>2</jats:sub>‐nanofiller‐modified PMMA. © 2018 Society of Chemical Industry</jats:p>
