A new and simple fabrication technique was successfully demonstrated in the fabrication of a novel multistructured flat fiber in the form of a doped flat fiber with dual airholes. This proof of concept fabrication technique uses only a drawing tower where an arrangement of solid rods and capillaries were attached inside a preform using a simple holder. The fabricated doped flat fiber with dual airholes had a dimension of 165 µm × 33 µm and the airhole diameter was 11.2 µm. Optical characterization demonstrated that the core had good light guiding capability with no light leaking to the adjunct of the cores as the capillaries in between the cores were not collapsed. The new fabrication technique is simple, cost-effective and allows a flexible core structure arrangement using glass rods and capillaries with different refractive indices. This flexibility allows a wide range of complex multistructured flat fibers to be fabricated and the ability to fabricate core dimensions with accuracy for future light guiding devices and optical sensor applications such as a biosensor that requires analyte to flow in the airholes.

一种新型且简单的制造技术已成功地以具有双气孔的掺杂扁平纤维的形式在新型多结构扁平纤维的制造中得到了证明。此概念验证制造技术仅使用拉丝塔，在拉丝塔中，使用简单的固定器将实心棒和毛细管的布置连接到预成型坯内。制成的具有双气孔的掺杂扁平纤维的尺寸为165μm×33μm，气孔直径为11.2μm。光学表征表明，该芯具有良好的导光能力，并且由于芯之间的毛细管没有塌陷，所以没有光泄漏到芯的附件。新的制造技术简单，经济高效，并允许使用具有不同折射率的玻璃棒和毛细管进行灵活的芯结构布置。
