Slit the end of a waveguide, flare to 1.0x0.75 to feed a dish.

Based on deeply-etched SiO2 ridge waveguides which support sharp bendings, a compact multimode interference power splitter was designed.

An idea is proposed that light-wave modulated only in claddings.

为此提出了一种在波导包层中调制光波的设想。

And the solution was used for waveguide analysis to G.655 fiber with three claddings and G.656 fiber with five claddings, and the result agrees well with the values by experimental measurement.

该解析法分别被用于三包层G.655光纤和五包层G.656光纤的波导分析，分析结果和实测值具有极好的一致性。

Because the light power in claddings is weaker than one in core, the overlap will weaken when modulation is realized only in cladding.

由于包层中光波强度比芯层中要弱，因此在包层中调制光波会引起场模交叠因子的弱化，但是优化计算发现，通过调节波导的尺寸尤其是芯层厚度可以控制交叠因子使其弱化程度降低到最小，在最优的情况下，场－模交叠因子可达0.89。

At the same time, the nonlinearity enhancement is correlative with pump and dopant concentration.

介绍了掺杂稀土元素的光纤非线性增强的机理，给出了几种常用的掺杂稀土元素光纤和波导的非线性数据。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
