摘要
从理论上对自聚焦透镜进行了分析,并论述了光在自聚焦透镜中的传播规律。进而提出了光纤准直器的设计结构,并通过实验验证,利用这种方法设计的光纤准直器具有低的插入损耗和高的回波损耗,能成功用于光环行器中。
This paper analyses the character of the graded index (GRIN)lens theoretically,and analyses the transmitting rule of lights in graded index(GRIN)lens.The structure of the collimator has been produced and verified by test that the collimator with this structure has lower insertion loss and higher return loss,which can be successful used in the optical circulator.
