Abstract: Systems for detection and compensation of modal dispersion in an optical fiber system including a multisegment photodetector coupled to an end of an optical fiber for detecting optical signals exiting the optical fiber and for converting the optical signals to an electrical output are provided. A representative multisegment photodetector includes a plurality of photodetector regions configured such that each of the plurality of photodetectors detects a portion of the plurality of optical signals exiting the end of the optical fiber and modifies the signal to reduce the affects of modal dispersion.

Abstract: Methods for detecting and compensating for multiple optical signals produced in a multi-mode fiber system are provided. A representative method includes detecting a plurality of optical signals radiating from an end of the multi-mode fiber by a multisegment photodetector having different detector regions that detect different portions of the plurality of optical signals, and modifying detected signal by the multisegment photodetector to reduce the affects of modal dispersion among the plurality of optical signals. Other methods also are provided.
