摘要
首先介绍了全矢量平面波法(FVPWM),重点分析和计算了二维三角排布的光子晶体平面内传播的带隙结构图,运用数值模拟出了对应的被测空芯光子晶体光纤(HC-PCF)平面内的带隙结构图。通过实验测量了HC-PCF以及石英棒的透射谱,根据数值计算得出了HC-PCF的相对透射谱。将实验计算得到的结果与理论模拟的结果进行了对比,发现两者在相近的归一化频率处有带隙,存在一致性。
A full-vector plane-wave methed（FVPWM） is introduced to calculate the photonic crystal in-plane photonic bandgap of a 2-D triangular structure. Using the numerical simulation,we can obtain the in-plane bandgap structure of hollow-core photonic crystal fiber. In our experiments,we measure the transmission spectra of a hollow-core photonic crystal fiber and silica red,and by using the numerical calculation the relative transmission spectrum of hollow-core photonic crystal fiber can be gotten. Compared with the theory simulation,we find that the experimental result is accordant with the simulation,they have the same bandgap in the same normalized frequency.
