摘要
为了解决包层为蜘蛛网结构的空心塑料光纤(POF)与单模石英光纤的耦合问题,采用了在两根光纤间插入倒锥透镜型光纤端头的方法,分析了光线在该光纤端头中的传播过程,并对其进行了数值仿真,计算出了耦合效率,给出了光纤端头的最佳耦合长度。
To solve the problem of coupling between cobweb cladding structure hollow-core fiber and single mode silica fiber, a length of fiber with converse taper lens is used to connect them. The propagation process of light ray in the converse taper lens is analyzed and simulated numerically. The coupling efficiency is calculated. And the optimum coupling length of the fiber with converse taper lens is given.
