匹配液的折射率对光纤定向耦合器分光比的影响

Influence of reractive index of matching liquid on branching ratio of optical fiber directional coupler

本文从理论和实验二个方面研究了光纤定向耦合器中使用不同折射率的匹配液对其分光比的影响。做出了分光比在1/1～1/30之间变化的光纤定向耦合器。

The effect of refractive index of matching liquid on the branching ratio of optical tiber directional coupler is discussed theorelically and experimenfcly. The fiber directional coupler with branching ratio of 1/1～1/30 has been fabricated.
