optical directional coupler meaning in Chinese

光定向耦合器
光方向耗合器
光学定耦合器

In the paper , some factors are studied such as ratio of soliton and signal wavelength , linear refractive - index of media and coupling length which have influence on the performance of the steerable all - optical directional coupler
研究了孤子波和信号光波长之比、器件长度及介质的线性折射率对光控可变定向耦合器性能的影响。
Based on the guidemode characters of dark spatial soliton waveguides and the theory of coupling between two waveguides , a kind of steerable all - optical directional coupler using dark spatial soliton waveguides is suggested
摘要基于空间暗光孤子诱导波导的模式特性以及光波在波导间耦合理论，提出了一种实现光控可变定向耦合器的方法。
