We present a novel fiber type with a trilobal, non-circular cross section. The fiber is designed for illumination purposes with a special shape in order to form 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 illumination purposes.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
