Abstract
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.
