提出了一种改进的控制多芯光纤各芯入射光功率分配比的方法。该方法是将多芯光纤与普通单模光纤在纤芯对准的条件下熔接后，将多芯光纤拉锥成双锥形状。在建立耦合理论模型和分析的基础上，提出了控制方法，并对控制结果进行了理论和实验验证。最后，这种入射光功率分布控制方法为多芯光纤器件和传感器提供了有益的和潜在的应用前景。
We propose an improved method to control the incident light power distribution ratio in each core of a multi-core optical fiber. This method is realized by tapering the multi-core fiber to be a bi-tapered shape after fusing the multi-core fiber with a normal single mode fiber on the condition of core alignment. Base on a coupling theoretical model and analysis, the controlling method is introduced, and the results are demonstrated by both theory and experiment. Finally, this incident power distribution controlling method provides a helpful and potential application prospect for multi-core optical fibers devices and sensors.
