Mode effective index的意思|示意

The properties of long period gratings in photonic crystal fibers (PCFLPG) are systematically analyzed by the improved full-vector effective index model and the coupled mode theory.

将修正的矢量等效折射率模型和耦合模理论相结合，系统地研究了光子晶体光纤长周期光栅(PCFLPG)的特性。

Starting with waveguide ray theory, the condition for single-mode waveguide is derived, and design of single-mode strip waveguide is accomplished with effective index method.

从导波的射线理论出发，导出了波导单模条件，运用有效折射率法完成了单模波导的优化设计。

The effective index refractive of every mode is 2.0044, 1.7098, measured by prism coupler method.

利用棱镜耦合法测得了该薄膜中每条模所对应的有效折射率为2.0044和1.7098。

Then in analogy with the theory of step-index fibers, the effective index of the fundamental mode and the dispersion of PCF can be calculated simply.

然后通过用类似于阶跃折射率型光纤的理论，很容易计算出光子晶体光纤的基模模式折射率和色散。
