摘要

Although tunable fiber Bragg gratings are flexible and promising solutions for dispersion compensation, but we still have the problems of variable optical communication path characteristics, environmental fluctuations and the variety of applications, that require re-design and fabrication of fiber Bragg gratings for each case. An alternative novel technique of dispersion compensation based on adaptive fiber Bragg gratings scheme would overcome these problems. In this paper three different real time adaptive dispersion compensation schemes, are introduced; scheme based on pulse shape detection, scheme based on crosscorrelation detection and scheme based on pattern recognition.
