本文通过基于有限元法的全矢量模态求解器，研究了一种带有抗谐振硅芯环绕结构的改进三角型空芯光子带隙光纤（PBGF）的新型传输特性。首先，为了实现宽波长范围内的单模工作，提出了去掉1个气孔并进行膨胀的纤芯结构，并对其进行了结构优化。特别地，给出了由于表面模式的存在而阻止窄带传输的光纤结构参数和增强对空芯中功率的约束。为了实现最终的低损耗传输，对7单元PBGF进行了分析，结果表明，与常规型7单元PBGF相比，7单元PBGF不仅具有更低的约束损耗，而且与具有抗谐振核心环绕的常规19单元PBGF相比，硅环中的功率分数更低，具有有效的单模工作特性。
In this paper, we study the novel propagation properties of an improved triangular-type air-core photonic bandgap fiber (PBGF) structured with an anti-resonant silica core surround, through a full-vector modal solver based on the finite-element method (FEM). At first, to realize a single-mode operation over a wide wavelength range, the fiber whose core is constructed by removing 1 air-hole and expanded is proposed and structurally-optimized. In particular, the structural parameters for the fiber that prevent the narrow-band transmission due to the existence of the surface modes and enhance the confinement of the power in the air-core are presented. For the realization of an ultimate low loss transmission, a 7-unit-cell PBGF is analyzed and we show that the 7-unit-cell PBGF can achieve not only lower confinement loss than that of regular-type 7-unit-cell PBGF, but also lower power fraction in the silica-ring when compared with the regular 19-unit-cell PBGF with an anti-resonant core surround, exhibiting an effectively single-mode operation.
