设计并研究了对光纤侧面加工的方法，使光纤侧面发光，从而获得了液晶显示器背光模组所需要的多发光点结构的激光光源。模拟分析了对光纤侧面加工时不同孔深、孔面积、孔几何结构等参数对光纤光场的影响，得到了各个出光点对应光场照度最大值在5%均齐度范围内的光场。

The method of side-surface process of fiber is designed and studied to make the fiber side lighting, then the laser source of multi-spot structure required by liquid crystal display backlight module is obtained. The effects of different depths, areas and geometrical structures of hole on the optical field of the fiber during the side-surface process are simulated and analyzed. The light field is obtained that the uniformity of the maximum luminous intensity of each light spot is within 5% field.
