摘　　要：光纤在信息通信领域的研究越来越广泛,而光纤中的模式识别技术为光纤模式分类提供了一种简洁的方法。通过阶跃光纤中波动方程的标量解,对横电波(TE)模式,横磁波(TM)模式,混合波(HE,EH)模式进行分类,在此基础上对特种光纤如多包层Bragg光纤,光子晶体光纤等具有代表性的光纤进行了仿真研究。以先前研究者提出的模式分类方法为依据,结合模式的电场线分布图和Ez方向的电场强度分布图,提出了一种具有普适性的模式分类方法,有助于研究者对光纤做进一步的探究。Optical fibers are being studied more and more extensively in information and communication.Mode recognition technologies in optical fibers provide a concise method for fiber mode recognition. Transverse electric wave(TE) modes, transverse magnetic wave(TM) modes and mixed wave(HE, EH) modes are classified according to the scalar solutions of the fluctuation equations in step index fibers. Moreover, simulation studies are performed for representative optical fibers such as multi-clad Bragg fibers and photonic crystal fibers. And a universal mode classification method is proposed by combining the electric field line distribution of the mode and the electric field intensity distribution in the Ezdirection, which helps researchers to do further investigations on optical fibers.
