Abstract

We present a fiber-based illumination scheme with directed and controllable radiation patterns using a novel fiber type with a trilobal, non-circular cross section. The particular shape forms a distinct asymmetrical radiation pattern, which can be used to concentrate light on particular locations in order to cure resins or polymers, but can also find its applications for lighting purposes.
