摘　　要：以全矢量波动方程理论为基础精确地推导出HOF中矢量模式的色散关系表达式,电场分量Hz和Ez在空心、纤芯以及包层区域的表达式;并推导出模式的传播常数以及导模的横向电场的表达式;在此基础上,重点分析研究了改变空心光纤的主要参数对模式特性产生的影响,包括:有效折射率与波长、空心半径、纤芯厚度之间的关系以及包层数量的变化对模式特性的影响规律,为进一步研究和扩展空心光纤的应用提供了依据。Based on the full vector wave equations, the dispersion formulas of vetorial modes were accurately established, and the expressions of field components were deduced in the hollow region,core region and cladding region. Then, the transverse electric field of the fundamental mode and the propagation constant were investigated. Based on the above analysis, the characteristics of mode were analyzed in detail by changing the main parameters of HOF, such as, the relationship between nneff and wavelength, radius of air hole, thickness of core. The raw of mode characteristics based on the varying number of cladding provides a basis for further research and application of hollow fiber.
