在过去的几十年中，已经开发了许多新型光纤，以科普光通信中对带宽的不断增长的需求，并扩展光纤在其他领域的使用。这些光纤的一些特征是复杂的几何形状和多种材料，例如光子晶体光纤（PCF）、反谐振光纤（ARF）和多芯光纤（MCF）等。目前的制造方法通常需要冗长且复杂的预制件制造过程，这损害了预制件的机械完整性。已经探索了增材制造过程来解决光纤制造的当前缺点。近年来，直接墨水书写（DIW）1、立体光刻（SLA）2、数字光处理（DPL）3和激光粉末床融合（LPBF）4已被用于3D打印眼镜。此外，使用激光打印方法报道了具有复杂结构5和多种材料6的3D打印二氧化硅光纤5，6。在这项工作中，我们提出了3D打印掺铒石英光纤的制造DIW方法。3D打印预制件使用12wt%的疏水气相二氧化硅; 2wt%的聚二甲基硅氧烷（PDMS）; 85wt%的四甘醇二甲醚（Tetraglyme）和1wt%的氯化铒的复合混合物制成。使用3D打印机Ultimaker+ 2在室温下以40 mm/s的恒定打印速度将复合材料混合物存款成500µm厚的均匀层。生产印刷的绿色体，随后将其热处理成如图1所述的透明玻璃。3D打印的掺铒预制件被放置在氟化管内，该氟化管用于提供与光纤的折射率对比。多模掺铒光纤被拉制为OD为100µm，纤芯直径约为40µm。使用能量色散X射线光谱（EDX）对光纤进行的成分分析证实了铒离子掺入到二氧化硅玻璃中。使用白色光源（WLS）来评估芯区中的Er 3+吸收。生产的3D打印光纤在980 nm处的吸收率为62.98 dB/m，在1535 nm处为151.49 dB/m，如图2所示。更多的光学表征结果将在会议上公布。
Over the past decades, 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. 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. In recent years, 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. Moreover, 3D printed silica optical fibres with complex structures5 and multiple materials6 were reported using laser printing method5, 6. In this work, we present the fabrication of a 3D printed Er-doped silica optical fibre by DIW method.The 3D printed preform was fabricated using a composite mixture of 12wt% hydrophobic fumed SiO2; 2wt% Polydimethylsiloxane (PDMS); 85wt% of tetraethylene glycol dimethyl ether (Tetraglyme), and 1wt% of erbium chloride. A 3D printer, Ultimaker+ 2, was used to deposit the composite mixture in uniform layers of 500µm thickness and a constant printing speed of 40mm/s at room temperature. A printed green body was produced, which is subsequently heat treated to a transparent glass as described in Fig 1. The 3D printed Er-doped preform was placed inside a fluorinated tube that was used to provide the refractive index contrast to the fibre. A multimode Er-doped optical fibre was drawn with an OD of 100µm and core diameter of~ 40µm. The compositional analysis using energy-dispersive X-ray spectroscopy (EDX) on the fibre confirmed the incorporation of erbium ions into the silica glass. A white light source (WLS) was used to evaluate the Er3+ absorption in the core region. The produced 3D printed optical fibre presents an absorption of 62.98 dB/m at 980nm and 151.49 dB/m at 1535nm, as shown in Fig 2. More optical characterisation results will be presented at the conference.
