Propagation of light in a square-lattice hollow-core photonic crystal fibre is analysed as a model of guidance in a class of photonic crystal fibres that exhibit broad-band guidance without photonic bandgaps. A scalar governing equation is used and analytic solutions based on transfer matrices are developed for the full set of modes. It is found that an exponentially localised fundamental mode exists for a wide range of frequencies. These analytic solutions of an idealised structure will form the basis for analysis of guidance in a realistic structure in a following paper.
作为一类无光子带隙的宽带导光光子晶体光纤中导光模型，分析了光在方形晶格空心光子晶体光纤中的传播。使用标量控制方程，并基于传输矩阵为全套模式开发了解析解。发现对于很宽的频率范围存在指数局域化的基模。这些理想化结构的解析解将作为后续论文中实际结构导光分析的基础。
