It is often convenient to use an "effective guide index. " 采用“波导有效折射率”是方便的。
We introduce normalizations that combine several guide parameters . 我们需要引入由几个波导参数组合的归一化量。
The refractive index n(x) varies gradually over the cross-section of the guide . 折射率n（x）在波导截面内是逐渐变化的。
In general, an inorganic residue is much more detrimental to the operation of the waveguide . 一般，无机残留物对波导使用的危害要大得多。
We discuss in more detail the application of the coupled mode formulas to scalar waveguide deformations . 我们将详细讨论耦合模公式对标量波导畸变的应用。
Other coupling schemes permit a prescribed proportion of the energy to be coupled from one to the other waveguide . 其它耦合方法允许指定份额的能量由一个波导耦合到另一个波导中。
Because gas lasers were often used as the light source, their beam had to be coupled into the thin-film wave guides . 由于气体激光器常用作光源，故必须将其光束耦合到薄膜波导中去。
The linear guide shown in fig. 3. 226 couples to the planar guide via the evanescent field which appears in the gap between the two guides . 图3226所示的条形波导通过出现在两波导间隙的消失场同平面波导耦合。
Numerical calculations have been made for wave-guides with a core of rectangular cross-section embedded in a uniform surround of lower refractive index . 对于掩埋在较低折射率的均匀介质中的距形截面芯子的波导曾作过数值计算。
It has been suggested that both the nidge guide, and the strip-loaded guide can be fabricated with relaxed requirements for resolution and edge roughness . 已有人提出，如果放宽分辨本领和边缘光洁度的要求，便能制备脊形波导和条载形波导。
