In this paper, when assuming a Gaussian near field distribution on the cross section of single-modefiber, it has been derived theoretically that the far field is also a Gaussian distribution.
本文在假定单模光纤横端面上的近场为高斯分布的前提下，从理论上导出了其远场分布也是高斯分布。

Through experiments, the coupling of singlemodefiber and waveguide switches has been researched thoroughly, and experimental devices have been designed.
通过实验，深入研究了单模光纤与光波导开关的耦合封装，设计出封装用的实验装置。
