Both mode coupling and mode distortion in the step-indexfiber are studied theoretically in order to gain the effect of mode distortion on the beam quality.
为了研究模场畸变对于大模场光纤光束质量的影响,理论研究了阶跃光纤的模式耦合和模场畸变的特性。

Then the mode series of stepindex planar dielectric waveguide and circular optical fiber are studied, including propagation modes and radiation modes.
接着推导了阶跃折射率平面介质波导和圆光纤的正交模式——包括束缚模式和辐射模式。

A simple method for measuring equivalent stepindex (ESI) parameters of the single mode fiber is presented.
