| 摘 要： | 根据能量积分法计算了球透镜用于激光二极管(LD)与单模光纤(SMF)之间耦合的耦合效率,并对其进行研究。结果表明:当采用单球透镜时,所带来的轴向偏差为±30 μm,横向偏差为±1.0 μm,沿着X-Y平面的轴向倾角偏差为±1.2°;当采用双球透镜时,角向偏差最大,横向偏差次之,轴向偏差最小。

| Abstract: | The coupling efficiencies of the ball lenses used in coupling of the laser diode(LD) and single mode fiber(SMF) were calculated and researched by a energy integration method. Research results indicate that when the single ball lens is used in the LD-ball lens-SMF system,the axial alignment tolerance is ±30 μm,the lateral alignment tolerance is ±1.0 μm and the tilting on the X-Y plane pivoting at the fiber tip is ±1.2°. When the double ball lenses are used in the LD-ball lenses-SMF system,the coupling loss of the tilting tolerance is maximum,the coupling loss of the lateral alignment tolerance is smaller than that of the tilting tolerance and the coupling loss of the axial alignment tolerance is minimum. |
