Abstract

3D printed preform by DIW was used to produce an Er-doped silica fibre fabricated. The fabrication method and optical features of the doped fibre are reported. Its absorption of 62.98dB/m at 980nm and 151.49dB/m at 1535nm and lifetime with a pulse width of 10ms are consistent to a Er-dope fibre produce in a conventional fabrication process. This data supports the paper '3D printed Er-doped silica fibre by Direct Ink Writing' presented at the 9th EPS-QEOD Europhotonic Virtual Conference that took place 30th August-4th Sepetember 2020

  • The authors would like to acknowledge the contributions from the UK Engineering and Physical Sciences Research Council award: EP/M020916/1; and CONACyT-Mexico awards: CVU607008 and CVU377962

  • The current fabrication methods often require a lengthy and complex preform fabrication processing that compromise the mechanical integrity of the preform, Additive manufacturing processes have been explored to tackle the current drawbacks of optical fibres fabrication

  • Direct ink writing (DIW)1, Stereolithography (SLA)2, digital light processing (DPL)3, and laser powder bed fusion (LPBF)4 have been used to 3D print glasses

Summary

Introduction

The authors would like to acknowledge the contributions from the UK Engineering and Physical Sciences Research Council award: EP/M020916/1; and CONACyT-Mexico awards: CVU607008 and CVU377962. Many new types of optical fibres have been developed to cope with the ever-increasing demand for bandwidth in optical communications, and to extend the use of optical fibers in other fields. Some of the features of these optical fibres are complex geometries and multiples materials such as photonics crystal fibres (PCFs), anti-resonant fibers (ARFs) and multicore fibres (MCFs), among others.
