分光比连续可调的光纤定向耦合器

Optical Fiber Directional Coupler with Continuously Variable Branching Ratio

讨论了耦合面积对耦合器分光比的影响，从理论上进行了计算，并实际制作出分光比连续可调的光纤定向耦合器。

A detailed description of the effect of coupling area on the branching ratio of optical fiber directional coupler is given. The effect is calculated theoretically. The fiber directional couplers with continuously varible branching ratio have been fabricated.
