摘要

本文研究了一种基于聚合物波导的多模光纤紧凑型受限模发射(RML)器件的性能要求。我们证实了MMF发射端较小的光斑尺寸对于提高有效模态带宽(EMBc)是必要的，而较低的数值孔径并不总是允许高EMBc。此外，我们还利用光束传播方法模拟确定了基于聚合物波导的RML激励器的设计准则。

Application of GI polymer optical waveguide to coupling devices between multimode fiber and VCSEL

In this paper, required specifications to a polymer waveguide based compact restricted mode launch (RML) device for multimode fibers are investigated. We confirm that a smaller spot size on the MMF launch end is necessary to enhance the effective modal bandwidth (EMBc), whereas a lower numerical aperture does not always allow the high EMBc. In addition, we determine the design guideline of polymer waveguide based RML exciters using the beam propagation method simulation.
