Abstract

D-shaped fiber is widely used in optical fiber sensing due to its special structure and excellent performance. Traditional manufacturing methods for D-shaped fiber are mechanical polishing and chemical etching. These methods have some disadvantages, such as low processing efficiency, and introduction of sub-surface damage layers or impurities. Laser ablation technology, as a non-contact high-efficiency technology, has been applied in optical fiber processing. The CO₂ laser was chosen as the heat source due to the strong absorptivity of glass for a laser with a wavelength of 9-11 μm. In this paper, we reported a new method of D-shaped fiber manufacturing based on CO₂ laser and study the effect of processing parameters on the surface morphology.
