摘要

我们已经开发了一种检测技术，以减少DMD的影响，而不会牺牲与使用多模光纤相关的优点，例如校准公差和易于制造。我们的方法是空间分辨均衡(SRE)的一个简单实现，它使MMF链路的带宽加倍。利用过填充发射条件，利用MMF发射光信号的空间分集。我们使用SRE探测器，这是一种InGaAs金属-半导体-金属(MSM)器件，放置在距离光纤端400 /spl mu/m处。

Spatially resolved detection for enhancement of multimode-fiber-link performance

We have developed a detection technique to reduce the effect of DMD without sacrificing the advantages, such as alignment tolerance and ease of manufacturing, related to the use of multimode fiber. Our method is a simple implementation of spatially resolved equalization (SRE) that doubles the bandwidth of MMF links. Using an overfilled launch condition, we exploit the spatial diversity of the optical signal emitted from the MMF. We use a SRE detector, an InGaAs metal-semiconductor-metal (MSM) device placed 400 /spl mu/m from the fiber end.
