Abstract
In this paper a straightforward method is proposed to determine the MPD within a given multimode fiber. The method combines Gloge's mode loss theory with new assumptions about the MPD, as well as a simple experiment which involves measuring the amount of power which survives a series of increasingly sharp bends. Using this technique, the most likely MPD within a fiber can be derived before and after the addition of a sensor.
