保偏双光纤准直器的研究与设计

The Research and Design of Polarization-maintaining Dual Fiber Collimator

从理论分析了光在自聚焦透镜中的传播性质 ,进而提出了保偏双光纤准直器的设计和研制。实验结果表明 ,该保偏双光纤准直器具有良好的插损、回损等性能 ,并且能成功的运用于偏振光合束器中。

A theoritical analysis about the transmitting characteristic of lights in Graded index(GRIN) lens was given.The researching and designing of a kind of polarization maintaining dual fiber collimator was discussed.Result shows that it have good performance in insertion loss and return loss and successful application in polarization beam combiner.
