我们回顾了不同特种光纤之间的光纤接头处的基本波导光学及其在接头经历热处理时的扩散特性。然后,我们描述了光耦合技术,包括热扩散和光纤锥形,以实现最小的传输损耗通过光纤接头。讨论了扩散引起的光耦合特性的变化以及光纤锥度比和锥度长度的影响,并给出了应用实例。
We review fundamental waveguide optics at a fiber joint between dissimilar specialty fibers and its diffusion characteristics when the joint experiences thermal treatment. We then describe optical coupling techniques including thermal diffusion and fiber tapering in order to achieve minimum transmission loss through the fiber joint. We discuss the optical coupling property change due to diffusion and the effect of fiber taper ratio and taper length with application examples.
