The variation rules of coupling-length with both wavelength and air holes have been found:for a given twin-core photonic fiber, coupling-length decreases with increasing wavelength;
分析了耦合长度随光波长、孔半径变化的一般规律；当双芯光子晶体光纤的结构一定时，耦合长度随波长增大而减小；
A comb-filter based on Mach-Zehnder interferometer (MZI) is experimentally fabricated by splicing a section of single mode twin-core fiber (TCF) between two single mode fibers (SMFs).
通过将一根单模双芯光纤熔接在两根单模光纤之间，实验制得全光纤马赫曾德尔干涉仪型梳状滤波器。
Based on the theoretical analysis of the principle of the FBG current measurement, the magnetostrictive effect of GMM, and the interrogation technology of twin-core fiber filter are introduced.
在介绍超磁致伸缩材料的磁致伸缩效应、光纤光栅检测电流原理以及双芯光纤滤波器解调原理的基础上，借助超磁致伸缩材料和光纤光栅等构建了电流测量单元。
The Dark Twin does not have a liquid core, but at one time did have this, as all planets coalescing from a Big Bang are first gaseous, then liquid, and then finally solidifying as they cool down.
黑暗孪星没有液态核心，但曾有一段时间它的确也有液核，因为所有行星是从宇宙大爆炸的气体凝聚，然后液化，最终降温固化而成的。
