摘　　要：对聚甲基丙烯酸甲酯(PMMA)芯聚合物光纤的临界弯曲半径进行了测试,利用光栅单色仪对采用不同尺寸滤模器的光纤出射光谱进行了测量。结果表明,PMMA芯聚合物光纤滤模器设计的最佳尺寸为半径1.5cm左右,且光纤缠绕圈数对滤模效果影响不大。The critical bending radius of PMMA polymer optical fiber is measured, By using grating monochromator, the exiting spectrums of the mode filters with different dimensions are measured. The experimental results show that the optimal dimension for PMMA fiber mode filter is about 1.5 cm in radius, and the winding laps has little affection on the filtering effect.
