摘要
单模光纤与毛细管光纤(COF)的侧抛耦合不会破坏COF的中央空气孔,使COF可以很方便地用作原子导引或采样管。实验研究了单模光纤与一种新型COF的侧抛耦合,并证明了该种耦合方法切实可行。通过解析方程计算了侧抛光纤剩余包层的厚度与耦合光功率的定量关系,为COF侧抛耦合的进一步研究奠定了基础。另外,侧抛耦合方式可使COF或其他类似微结构光纤应用更广。
Abstract
Side-polished coupling cannot damage the central air hole of capillary optical fiber(COF), so that COF can be conveniently used as atomic guiding or sampling tube. Side-polished coupling of single mode fiber and a novel COF is studied by experiment. And the results prove the coupling method is feasible. By analytical equations, the quantitative relationship between the thickness of the residual cladding and the coupling optical power is calculated. It may be the basis for further study on the side-polished coupling for COFs. Side-polished coupling method also can expand the application of COF or other similar microstructure fiber.
